Ferromagnetic Material of the Nearly Half-Metallic Alloy Co₂TiGa

Abstract:

The structure, electronic and magnetic properties of full-Heusler alloy Co₂TiGa are investigated by means of the full potential linearized augmented plane-wave method. Our results show that the ground state of Co₂TiGa is of the nearly half-metallic ferromagnetism with a magnetic moment of 1.00218 μ_B per unit cell, which are contributed by the atoms Co and Ti. Meanwhile, the spin polarization around the Fermi level is up to 93.2%, almost 100%, which indicates that full-Heusler alloy Co₂TiGa with the well magnetism and spin polarization would be possibly applied to the field of the material engineering and information technology.
