摘要：

The electronic band structures, density of states (DOS) and the magnetic moments have been compared and analyzed to propose the half-metal ferromagnetic nature of NiTbSb. For this, density functional theory based full potential linearized augmented plane wave method has been used. DOS and band structure results show that 3d states of Ni and 4f states of Tb atoms overlap each other throughout the Ni-3d bands, suggesting substantial hybridization between them. The presence of Sb atom influences the hybridization between Ni and Tb atoms. A qualitative agreement with the earlier results has been observed.
