Study of electronic structures of CeRu2 Si2 by LDA + U method

Michi To Suzuki, Hisatomo Harima

Research output: Contribution to journalArticlepeer-review


Electronic structures of CeRu2 Si2 are calculated by LDA + U method extended for magnetic system with strong spin-orbit interaction. The LDA + U method significantly improves the character of the ground state in the nonmagnetic state. The calculated electronic structures explain change of physical properties associated with metamagnetic transition. The Fermi surfaces after metamagnetic transition were reproduced well in this method, although the continuous change of electronic structure by metamagnetic transition is not described.
