### 抜粋

We have studied the electronic structure of (Formula presented) with (Formula presented), 0.12, and 0.18, which compositions cover the paramagnetic, metamagnetic, and ferromagnetic phases, by means of photoemission and inverse-photoemission spectroscopy. With Al substitution, broad peaks near the Fermi level (Formula presented) are shifted upwards and one of them crosses (Formula presented) as predicted by band-structure calculation, although the peaks are much broader than predicted by the calculation. The overall Co (Formula presented) band is narrow and has a high binding energy tail compared to the band-structure calculation, indicating significant electron correlation effects in the Co (Formula presented) band. In order to explain these observations, model self-energy corrections have been applied to the band density of states. The lower energy scale of the self-energy is found to lie in the same range as the characteristic temperature of the magnetic susceptibility.
