Electronic structures of potential permanent magnets La(Co{sub 1{minus}x}Fe{sub x}){sub 13} (x = 0, 0.2) have been investigated using photoemission spectroscopy. The partial spectral weight (PSW) distributions of the La 5d and T 3d (T = Fe, Co) electrons are determined and compared to the calculated angular momentum projected local densities of states (PLDOSs). The extracted La 5d and Co 3d PSWs suggest the hybridization between Co 3d and La 5d states and a weak Co 3d Coulomb interaction in this system. The experimental T 3d PSWs of La(Co{sub 1{minus}x}Fe{sub x}){sub 13} with x = 0 and x = 0.2 are found to be consistent with the predicted changes in PLDOSs with a small substitution of Fe for Co in LaCo{sub 13}, obtained in the virtual crystal approximation.
