Contribution to the study of the CoFeTi Asquaternary Heusler material's structural, electronic, and magnetic properties

Abstract

By simulating the structural, electronic, and magnetic properties of the QuateryCoFeTiAs Heusler compound, we presented a theoretical investigation in this work The calculations were performed using the generalized gradient (GGA) approximation and the  WIEN2k code's application of the augmented plane wave method (FP-LAPW)which is based on density functional formalism (DFT). The results are consistent with important theoretical calculations.Our results showed that this compound conforms with the (Slater-Pauling) Mtot = (ZT - 24) μ_B rule and is a half-metallic material.
