Within a continuum model based on the microscopic magnetic symmetry of Ni 2+ ion (spin S = 1) in the metal-oxide compound La 2 NiO 4+δ, a theoretical analysis is made of the stability of antiferromagnetic long-range order under the effect of oxygen interstitials at δ ≪ 1. It is shown that the Néel temperature dicreases significantly with growing δ though does not become zero, in contrast to that in the structurally isomorhic compound La 2 CuO 4+δ (but Cu 2+ spin S = 1/2).

Populist parties’ dazzling success has been registered in numerous new and old Member states for a while; populism has occupied a crucial position in Romanian politics since the onset of post-communism, with constant emphasis on the iconic role of the people in the democracy, the role of the leader in public statements and in the party’s organisation, the promotion of Manichean and simplistic solutions to the political/economic agenda, as well as the constant use of direct and emotional appeals, etc. Within this framework, the research question is: can Romanian populism be understood as a “temporary” problem of adjustment and adaptation, or is it a deeper structural effect, which requires further attention, considering its potential threats to the stability of the post-communist regime? Considering populism as a multi-faceted phenomenon that cannot be traced to a unique structure or a single/specific agency, the conclusions suggest the existence of an osmotic relationship between deep-rooted populism and democracy in Romania, in the sense that it is difficult to clearly identify which is the cause of the other. As such, the Romanian specificity stems from the constancy of this phenomenon and, above all, from its potential for contamination: populist cries become national mainstream catchwords.

We present results of specific heat and magnetic susceptibility measurements as function of temperature and magnetic field on the rare-earth compound CePd3In2. Known to order antiferromagnetic below 2.1 K, we discuss the influence of magnetic field on the stability of the magnetic order.

Abstract Using ab initio calculations, the phase stability of modulated and tetragonal martensitic structures in Ni43.75Co6.25Mn43.75(In, Sn)6.25 Heusler alloys with different magnetic order is investigated. The stability against the segregation is considered by a method for generating all possible decay reactions assuming the calculated ground state energies of each composition. It is shown that the highest probable stability under equilibrium conditions is demonstrated by alloys with tetragonal martensitic structure in accordance with reactions: Ni35Co5Mn35In5 → 25Mn + 35Ni + 5Mn2InCo and Ni35Co5Mn35Sn5 → 5CoSn + 35Mn + 35Ni.
