Mixed-cation driven magnetic interaction of interstitial electrons for ferrimagnetic two-dimensional electride

Magnetism of pure electrons is fundamental for understanding diverse magnetic phenomena in condensed matters but has not been fully investigated in experiments due to the lack of a tractable model system. Such an exotic material necessitates an exclusive magnetic interaction of electrons being devoid of orbital and lattice degrees of freedom. Here, we report the two-dimensional mixed-cation [YGdC]2+∙2e− electride, showing ferrimagnetic nature from the direct exchange interaction of magnetic interstitial electrons in interlayer space. We identify that magnetic interstitial electrons are periodically localized in octahedral and tetrahedral cavities between 2D cationic Y2−xGdx arrays. The mixed configuration of non-magnetic and magnetic cations in cavities induces divergent spin states and interactions of magnetic interstitial electrons, in which their direct exchange interaction overwhelms the interactions with magnetic cations, triggering the ferrimagnetic spin-alignment. This discovery facilitates further exploration of magnetic electrides and nurtures the study of two-dimensional magnetism of layered crystals and electron phases.

A Rare Earth Metallocene Containing a 2,2’-Azopyridyl Radical Anion

Introducing spin onto organic ligands that are coordinated to rare earth metal ions allows direct exchange with metal spin centres. This is particularly relevant for the deeply buried 4f-orbitals of...

The Single Digital Gateway Regulation as an Enabler and Constraint of Once-Only in Europe

The adoption of the Single Digital Gateway Regulation is a gamechanger in European e-government. For the first time, it creates a horizontal, non-sector specific legal framework for the direct exchange of digital evidence between public administrations in different Member States. However, these exchanges require public administrations to have a certain degree of trust in each other, which is built on a shared legal basis. The Single Digital Gateway Regulation achieves its goal of creating a legal basis and establishing trust, but also builds in a number of explicit and implicit legal constraints. These will help make the once-only principle in Europe a reality, but also enshrine limitations that will require revisions and expansions of the Regulation at some point in the future. This paper examines the genesis of the Regulation, its legal choices and priorities, the resulting implications and limitations, and potential challenges for the future.

Value of Goods During the Period of Russian Economic Transit Based on Barter Ads Analysis

The study proposes a method for modeling consumer perceptions of citizens during the late Soviet period and early 1990s based on newspaper ads for direct exchange of goods. The toolkit of social network analysis is used for modeling. To determine the range of status goods and the economic behavior features of citizens moving from the era of shortage to the era of market relations is possible thanks to created semantic networks.

Psychedelic Telepathy: An Interview Study

This article presents an interview study of telepathic experiences induced by psychedelic drugs, with the aim of broadening our understanding of the nature and characteristics of such experiences. Of 40 psychedelics users interviewed about their experiences, 16 reported some form of psychedelic telepathy. Respondents were recruited at various online fora for individual interviews via private messaging. They reported three main types of telepathic communication: 1) an information-exchange type of telepathy that often enabled people to communicate in images as well as words; 2) a type sometimes referred to as telempathy that allowed for the direct exchange of feeling-states; 3) a state of self-dissolution and telepathic unity where one could not differentiate one’s own thoughts and feelings from those of the friend or partner. Some participants complained about the lack of privacy especially in the more intense forms of telepathic states, and were hesitant to repeat the experience, while others claimed they had become accustomed to such states and experienced them regularly. The article concludes that further studies are warranted, and suggests a research design for an experimental study of psychedelic telepathy.
