Electronic structure and the Fermi surface of ThRhIn$_5$ in comparison with uranium and transuranium compounds

Abstract

By using a relativistic linear augmented-plane-wave method, we clarify energy band structure and the Fermi surfaces of recently synthesized thorium compound ThRhIn$_5$. We find several cylindrical Fermi surface sheets, which are similar to those of CeTIn$_5$ (T=Ir and Co), PuTGa$_5$ (T=Co and Rh), and AmCoGa$_5$. We discuss such similarity among the compounds including rare-earth or actinide ions with different $f$ electron numbers.Comment: 2 pages, 2 figure, Proceedings of SCES'05 (July 26-30, 2005, Vienna
