Owing to the metallic nature of majority spin and semiconducting minority spin, the In1−x V x P compounds exhibit a half-metallic character with total magnetic moments of 2 μ B, while the B1−x V x P has metallic nature for all concentrations. The results of exchange parameters revealed that exchange coupling between vanadium atoms and the conduction band is ferromagnetic, confirming the magnetic feature of In1−x V x P and B1−x V x P. From our findings, we have predicted that the In1−x V x P alloys seem to be potential materials for spintronics.Lire moins >
