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