Magnetic behavior of curium dioxide with non-magnetic ground state
Abstract
In order to understand magnetic behavior observed in CmO2 with non-magnetic ground state, we numerically evaluate magnetic susceptibility on the basis of a seven-orbital Anderson model with spin-orbit coupling. Naively we do not expect magnetic behavior in CmO2, since Cm is considered to be tetravalent ion with six 5f electrons and the ground state is characterized by J=0, where J is total angular momentum. However, there exists magnetic excited state and the excitation energy is smaller than the value of the Land\'e interval rule due to the effect of crystalline electric field potential. Then, we open a way to explain magnetic behavior in CmO2.
