Abstract
We have investigated the electronic and magnetic structures of Heusler alloys L21 Mn2TiZ (Z=Al, As, Bi, Ga, Ge, Sb, Si, and Sn) using spin-polarized density functional theory within the generalized gradient approximation (DFT-GGA) for electron exchange and correlation. Our results show that the highly-ordered Mn2TiZ alloys have a half-metallic ferrimagnetic character at their respective equilibrium lattice constants. The calculated total magnetic moment is in good agreement with the Slater–Pauling rule, except for a small deviation.
