Crystal-Field Effects on Low-Frequency Susceptibility for Ce-Kondo System

抄録

The low-frequency dynamical susceptibility for the Ce-Kondo system is investigated on the basis of the local Fermi liquid theory at zero temperature. The effects of the crystalline field are studied precisely by means of the Bethe-Ansatz solution of the Anderson model, for the cases of cubic, hexagonal and tetragonal fields. It is shown that the magnetic relaxation rate of the f-electron is enhanced in general in the presence of the crystalline fields. The anisotropic properties of the relaxation are discussed for hexagonal and tetragonal fields as well.
