Abstract

Self-consistent linear muffin-tin orbital calculations are performed for CeAg. The electronic structure is calculated in the paramagnetic and ferromagnetic phase, for both the cubic and tetragonal symmetry. The presence of hybridization relevant to the Anderson lattice behavior, invoked to interpret the low-temperature properties of this compound, is confirmed. The comparison of the electronic structures of CeAg and of its f-less analog LaAg allows us to determine the localized part of the Ce 4f charge, amounting to ∼ 0.94 e/Ce, to be identified with the average f-occupation number in the Anderson model. A saturation magnetic moment of ≈ 0.78μB is found, which is essentially due to the Ce f electrons.
