Coercive force of double layer ferromagnetic materials

Peculiarities of the coercive force (CF) measuring of inhomogeneous ferromagnetic materials, in particular layered ones, are considered. The concept of effective CF of layered ferromagnetic materials is introduced. The analysis of the magnetic fluxes distribution in a double layer ferro-magnetic material during its reversal magnetization by an attachable transducer with a U-shaped core made of soft magnetic material is carried out. An analytical expression of the effective CF for such class of materials for the case of the same layers’ thickness and linear approximation of their demagnetization curves is obtained. It was found that the effective CF of a double layer ferromagnetic material is determined not only by the CF of its individual layers, but also by the values of their residual induction. Experimental verification of the obtained results was performed on experimental samples, which were collected from steel 08kp (sample # 1) and steel St3 (sample # 2) plates. Each of the samples was a stack of 6 plates each measuring 87×50×1 mm. With tight compression of the plates and complete elimination of the gaps between them, these samples can be considered as single layer ferromagnetic structures with a thickness of 6 mm. To model a double layer ferromagnetic material with the same layer thickness, sample № 3 was used. Its the upper part consisted of the three steel 08kp plates and the lower part – of the three steel St3 plates. To measure the magnetic parameters of these samples the KRM-Ts-MA type magnetic analyzer was used. The device permit to measure the CF, residual induction and other parameters of the hysteresis loops of ferromagnetic materials in the closed magnetic circuit by attachable type transducers with U-shaped core. The transducer used with the magnetic analyzer during the experiments had poles with an area of 16×32 mm and the distance between the edges of the poles: inner – 32 mm, outer – 64 mm. It is shown that the discrepancy between the calculated value of the effective CF of the double layer ferromagnetic material (sample # 3) from steel 08kp and St3 according to the obtained expression and the measurement results is about 3%. This confirms the adequacy of the proposed model of reversal magnetization of double layer ferromagnetic material and the correctness of analytical calculations.

Dialectics of Alienation and Abnormality

This chapter portrays dialectically intertwined issues of alienation (in the Frommian sense of estrangement from self and others), abnormality, anxiety, and authenticity. Giddens theorizes that modern society is undergoing a ‘transformation of intimacy’, where love and sex are freed from patriarchal traditions, and people increasingly value ‘pure relationships’ where authentic connection is the only motive and can be fully realised. We claim that this desire for authenticity extends beyond this in the society of the selfie, the persistent unrequited thirst for it directly clashes with the alienated status quo. ‘Authenticity strain’ haunts the social terrain with loneliness, anomie, and the threat of volatility and transgression of personal boundaries. The desire for authenticity, and the moral sense that surrounds it, dovetail with the frustrated voyeurism of life under the spectacle in the age of Web 2.0. Fromm says that the inability to genuinely connect with other people can inspire people toward sadomasochism instead, which primes them for authoritarian social movements. And once again we turn to Foucault, to describe his theories about the designation of ‘abnormal’ people. Today, the fear of abnormalities of self and Other, both inner and outer—of becoming or falling victim to predatory, psychologically unhinged Others such as cyberstalkers, violent obsessives, pedophiles with fake avatars, mass shooters, etc.—has become a rampant new nightmare. It is a nightmare that fuels a common desire for greater protection from ‘deviants’ and outsiders through an increase of coercive force, i.e., for authoritarianism.

Sovereignty, Territoriality, and Law

This chapter seeks to analyze the changing meaning of ‘peace’ under an early colonial regime which was perpetually at war. ‘Peace’ in early colonial South Asia no longer meant the absence of conflict, but rather a period when problems of war assumed an urgent significance. From paying soldier’s arrears incurred during military conflicts to disciplining them in times when the Company state was not formally at war—‘peace’ was no longer the opposite of war. Rather it was the fleeting opportunity to re-tool the apparatus of colonial war-making. Conquest did not occur in a legal vacuum. This chapter analyses debates about military law and its significance for the early colonial regime’s claims to sovereign authority. Jurisdictional jockeying between competing sources of law went well beyond the need to maintain military discipline. Examining these debates opens up an unexplored world in which we can understand important questions relating to the territoriality of early colonial rule, the legal personality of the Company state and efforts to compare Britain’s garrisoning of Ireland with the organization of coercive force in South Asia.

Discipline and Defence: The Military Influence on Policing and Imprisonment, c.1870-1913

<p>Discipline and Defence follows the influence of military discipline, tactics and personnel through New Zealand's police and prisons from the end of the New Zealand Wars until the eve of the Great War. At the beginning of this era, constables and prison guards were recruited almost entirely from the ranks of soldiers, and were used to "settle" Maori resistance to the growing Pakeha state by constructing infrastructure as well as wielding coercive force. As colonial society became increasingly settled by the 1890s, criticism of soldiers' drunken indiscipline coincided with an increasing separation between the police and military, although prisons remained under a military hand. However, the popularity of the Anglo-Boer War recreated the soldier as the epitome of virtuous manhood, and administrators once more sought former soldiers to fill the ranks of the police and prison service. Rising industrial strikes and labour's opposition to such popular militarism by 1913 brought an open conflict between these partially re-militarised institutions and strikers. Throughout the entire period, arguments over the correct form of discipline for New Zealand's men intersected with practical necessities to influence the ongoing role of the military in domestic policing and punishment.</p>

Composition of the Frenkel–Kontorova and Ising models for investigation the magnetic properties of a ferromagnetic monolayer on a stretching substrate

In the article, computer simulation on the behavior of a ferromagnetic thin film on a non-magnetic substrate by computer simulation is performed. The substrate is described by the two-dimensional Frenkel–Kontorova potential. The Ising model is used to describe the magnetic properties of a two-dimensional ferromagnetic film. The Wolf cluster algorithm is used to model the magnetic behavior of the film. A square lattice is considered for an unperturbed ferromagnetic film. Computer simulations show that mismatch of film and substrate periods results in film splitting into regions with different atomic structures. Magnetic properties for the obtained structure have been investigated. The hysteresis loop is calculated using the Metropolis algorithm. Deformations of the substrate lead to a decrease in the phase transition temperature. The Curie temperature decreases both when the substrate is compressed and when stretched. The change in phase transition temperature depends on the decreasing rate of exchange interaction with distance and the amplitude of interaction with the substrate. When the substrate is compressed, an increase in the amplitude of the interaction between the film and the substrate results in an increase in the phase transition temperature. The opposite effect occurs when the substrate is stretched. The hysteresis loop changes its shape and parameters when the substrate is deformed. Compression and stretching of the substrate results in a decrease in coercive force. The reduction in coercive force when compressing the substrate is greater than when stretching. The magnetization of the film is reduced by deformations at a fixed temperature.

Historical evolution of the judicial system of Ancient Russia in the aspect of customary law

The formation of the Russian procedural legal system is closely connected with its unique historical evolution. Russian Russian culture According to the Norman theory of the origin of the Russian nation, the Scandinavian culture is the most important source of early Russian culture. During the chaotic period of the tribe at the stage of primitive society, the Norman Varian was invited to Russia to reconcile the tribes of Russia and manage them, and this brought the Germanic custom to regulate the socio-economic and legal relations of various tribes. Since the formation of the ancient state of Russia, the ruling class has constantly strengthened the drafting of new laws and regulations, but customary law still dominates the legal system of the state. At the same time, ordinary norms in the system of customary law as a quasi-legal norm between morality and law have become an integral organic component of social customs and norms at all stages of Russian social development.During the period of Ancient Russia, the common custom of the Slavic people and the Norman Customary Law had a profound impact on the social life of ancient Russia. From the beginning of the 9th to the 17th century, customary law existed as the main legal source for regulating social relations in the late period of the development of Russian primitive society and in the earlier time of feudal society. His coercive force was based on the conviction that was widespread in the social community during this period, that is, "existing customs denote a reasonable basis". With the formation of the East Slavic state, the rulers began to work on drafting new legal norms, but inheritance is still mainly based on customs based on the clan system. As a result, as a rule of conduct recognized and guaranteed by the state, traditional customs gradually acquired a legal nature, and after that, positive law was formed. "Russkaya Pravda" is the most representative legal collection in the early years of the Russian feudal society, "The Truth of Ross", which was compiled according to the customs of the Eastern Slavs, and is the very fi rst positive law of ancient Russia.Before the appearance of formal law, customary law always played a role and coercive force as legislation, but the self-defense and insane methods of revenge obtained from it also caused social unrest. In order to stop personal self-defense and self-arbitrariness, as well as to strengthen ties between different regions, it is necessary to use the power of common law to unite the Principality into a whole. Although the new law does not exclude the original good customary norms, if there are no necessary penalties for violations, it will be destructive for the law. Therefore, it is necessary to give customary law a legal meaning and a compelling force, without changing the existing content of customary law.I must say that the German customs and the traditional customs of the Slavic people are intertwined in the historical codifi cation of Russian procedural law, forming a unique historical path of development of the procedural legal system of ancient Russia. Although national customs were recognized by the state in the form of positive law with the help of " Russian Truth”, and became the norm of justice and social norm on the basis of the guarantee of national coercive force, but this did not change the essence of customary law, but the form of positive law was given to it. As the modernization of the Russian judicial system moves into modern times, generations of legislators and lawyers are focusing on the study of national legal traditions and history, trying to discover the natural laws governing the development of the Russian legal system, and are constantly trying to make progress in the modern and modern process of judicial reform. The harmony of legislation, the borrowing of laws and national customs to a certain extent ensured a reasonable adjustment of national laws and norms of customary law.

Analysis of Remagnetization Processes of High-Anisotropic Alloy after Heat Treatment

The simulation of the Sm(Co, Fe, Cu, Zr)7.5 type alloy domain structure formation after various thermal treatments was carried out by FMRM program based on a phenomenological approach to the analysis of the uniaxial highly anisotropic ferromagnets demagnetization processes. It is shown that the domain structure of the alloy in the thermally demagnetized state expands as the coercive force of the alloy decreases. It is noted that the domains size increasing process is associated not only with a decrease in the coercive force but also with a change in the influence of the magnetostatic interaction.
