Abstract
We have used full-potential linearized augmented plane wave method in the stable Fm-3m phase to investigate the structural, elastic, magnetic and electronic properties of Co2VZ (Z=As, In). The optimized equilibrium lattice parameter in stable phase is 5.80Å for Co2VAs and 6.01Å for Co2VIn. Ferromagnetic behavior of both the alloys is explained by the spin resolved density of states. The exchange splitting due to Co and V atoms are responsible for the ferromagnetic behaviour. No energy gap is found in spin up state while an energy gap can be seen in spin down state, hence, showing half-metallic nature. Elastic stability is discussed through elastic constants. Thermodynamic properties of the alloys have been obtained by using the quasi-harmonic approximations. Boltzmann theory is employed to investigate the electronic transport properties of these alloys.
