Abstract

We have studied the electronic structure of Y(Co1-xAlx)2 with x = 0.0, 0.12 and 0.18, which compositions cover the paramagnetic, metamagnetic and ferromagnetic phases, by photoemission and inverse-photoemission spectroscopy. The spectra are compared with the density of states given by band-structure calculations. An agreement between experiment and theory was considerably improved by applying a self-energy correction to the band density of states.
