摘要：

We explain the anomalous magnetic behavior in the pseudobinary compounds of cubic Laves-phase Ce(Fe,M)2 (M = 3d, 4d, and 5d transition-metal atoms) in terms of d-f hybridization. Calculated cerium and iron moments in CeFe2 are found to be antiparallel such that mu-Ce/mu-Fe = -0.37, which is in excellent agreement with the recent experimental value of -0.3. The calculated l-projected density of states is utilized to explain in detail the nature of the hybridization (d-d-f) responsible for various anomalies in these pseudobinary compounds.
