Abstract
The results of a first-principles study of the magnetic and half-metallic properties of ordered Ca-Cr-As alloy with zinc-blende like structure are presented. The full-potential linearized augmented plane wave method is used in order to resolve the electronic structure of CaxCr1-xAs alloy, in which concentration of Ca atoms varies from 25% to 75% (x=0.25, 0.5, 0.75). The obtained results indicate that all the investigated compounds are half-metallic with magnetic moment determined by the Ca concentration. Particularly, it is found that Ca0.75Cr0.25As is a half- metallic antiferromagnet with no net magnetization.
