Microscopic Origin of Heisenberg and Non-Heisenberg Exchange Interactions in Ferromagnetic bcc Fe.

By means of first principles calculations, we investigate the nature of exchange coupling in ferromagnetic bcc Fe on a microscopic level. Analyzing the basic electronic structure reveals a drastic difference between the 3d orbitals of E_{g} and T_{2g} symmetries. The latter ones define the shape of the Fermi surface, while the former ones form weakly interacting impurity levels. We demonstrate ...

Variation of the exchange frequencies with density in bcc solid 3He

2014 We discuss the interpretation of recent pressure measurements in magnetic field performed by Van Degrift et al. In contrast with the authors, we think that these results are not in contradiction with the susceptibility measurements and give further arguments in favour of the multiple exchange model. We deduce the derivatives of the three and four particle exchange frequencies with respect ...

Fuzzy Derivations BCC-Ideals on BCC-Algebras

In the theory of rings, the properties of derivations are important. In [15], Jun and Xin applied the notion of derivations in ring and near-ring theory to BCI-algebras, and they also introduced a new concept called a regular derivation in BCI-algebras. They investigated some properties of its .In this manuscript, the concept of fuzzy left (right) derivations BCCideals in BCC-algebras is introd...
