Abstract
This paper reports calculations of the linear responses (the dielectric constant and the magnetic susceptibility) of an electron gas interacting through an exchange interaction with a set of localized magnetic moments. This allows one to account for the metal-semiconductor transition which has been observed in moderately doped EuO, in agreement with experimental data.Keywords
