Structural, electronic, magnetic properties and elastic anisotropy of New ferromagnetic Cu2CrZ (Z=Si and Ge) full heusler alloys

Abstract

In this paper, we have performed a first-principles study to investigate the electronic structure, magnetic, mechanic and anisotropic elastic properties of Cu2CrZ (Z=Si and Ge) Full Heusler alloys. The study of these characteristics shows thermodynamic and mechanical stability with cubic symmetry in our compounds and they also have an anisotropic character. The ground-state parameters, i.e., lattice constant, the bulk modulus and the electronic structure are calculated using the full-potential linearized augmented plane wave (FP-LAPW) approach to the density functional theory (DFT) within the generalized gradient approximation (GGA+WC) for the exchange and correlation potential. The objective is to seek stable metallic ferromagnet materials
