Antiferromagnetic phase transition in $C r_{2} A s$ via anisotropy of exchange interactions

arXiv:1902.03337

Abstract

The electronic structure of anti-ferromagnetic $C r_{2} A s$ is investigated. Anisotropy of exchange interactions between chrome sub-lattices is determined ( $J^{X} (C r_{I} - C r_{I I}) = 4.77 m e V, J^{Y} (C r_{I} - C r_{I I}) = - 6.36 m e V$ ). The behavior of exchange integrals from magnetic structure is analyzed.
