- Opis:
- In the paper density functional theory method was applied to explore the electronic and magnetic properties of the GdNiSb in low-temperature phase with cubic MgAsAg-type structure and in the high-temperature phase. The calculations were performed by first principles full-relativistic full potential local orbital method within the local spin density approximation. The calculations results show the metallic character of GdNiSb compound in the high-temperature phase with hexagonal $AlB_2$-type structure. For the low-temperature phase of the cubic GdNiSb system, they indicate a semiconducting behavior. The density of states below the Fermi level is greater in high-temperature phase than in low-temperature one, the calculated magnetic moment is in good agreement with an available experimental value.
