摘要：

In this paper, we performed an ab initio calculation of the different properties of the full-Heusler alloy Ti2VPb which is reported for the first time using the WIEN2k implementation of the full potential linearized augmented plane wave (FPLAPW) scheme. In order to study this compound for magneto-electronic applications we used the generalized gradient approximation (GGA) approximation for its mechanical properties but the MBJ-GGA to better investigate the electronic properties. Our results show that the Ti2VPb compound exhibits half-metallicity at its equilibrium lattice 6.548 angstrom but a metallic character would occur with an expansion of its lattice parameters to 6.85 angstrom.
