The review considers various groups of Heusler compounds, which can have the properties a semiconductor, half-metallic ferromagnet, spin gapless topological semimetal, and non-collinear antiferromagnet. In these “conventional” from point view crystal structure, unusual kinetic magnetic be observed, are caused by features their electronic structure (e.g., presence an energy gap for one projectio...
The natural nanomineral ferrihydrite is an important component of many environmental and soil systems and has been implicated as the inorganic core of ferritin in biological systems. Knowledge of its basic structure, composition, and extent of structural disorder is essential for understanding its reactivity, stability, and magnetic behavior, as well as changes in these properties during aging....
In a recent publication [Galanakis I et al 2006 Phys. Rev. B 74 140408(R)] we have shown that in the case of CrAs and related transition-metal chalcogenides and pnictides, crystallizing in the zinc-blende structure, the excess of the transition-metal atoms leads to half-metallic ferrimagnetism. The latter property is crucial for spintronic applications with respect to ferromagnets due to the lo...
Crystals of a cobalt(II) 3-amino-1,2,4-triazolate; Co(2)Cl(C(2)N(4)H(3))(3), 1 can be formed from a hydrothermal synthesis. X-Ray crystallography shows an extended 3-dimensional network structure within a hexagonal space group with a=9.9655(7) and c=7.7523(7) A. The data reveal an orientational disorder to the ligand. Structural considerations suggest that the ligand orientation is strongly cor...
