摘要：

Effects of symmetry breaking in the 4f orbital occupancy of Ce atom in ferromagnetic Ce compounds on the multiplet structures in the Ce 3d- and 4d-core photoabsorption spectra are discussed based on the impurity Anderson model. The calculation predicts a strong circular dichroism in the spectra even for a molecular field producing the 4f magnetic moment of 0.5µB. The interplay of the 4f-conduction band hybridization and the 4f spin-orbit interaction in the ground state is discussed in detail and the present dichroism is shown to be a good method to measure the spin and orbital contributions to the 4f magnetic moment. © 1990 IOP Publishing Ltd.
