Electronic Properties of Transuranium Compounds with HoCoGa-Type Tetragonal Crystal Structure
Takahiro Maehira, Takashi Hotta, Kazuo Ueda +1
By using a relativistic linear augmented-plane-wave method with the one-electron potential in the local-density approximation, we investigate energy band structures and the Fermi s…

Cooperative Jahn-Teller Effect on the Magnetic Structure of Manganese Oxides
Takashi Hotta, Seiji Yunoki, Elbio Dagotto
The magnetic structure of LaMnO is investigated on three-dimensional clusters of MnO octahedra by using a combination of relaxation and Monte Carlo techniques. It is found…
