Abstract
Magnetization curves of the localized-itinerant intermetallic system Gd 1− x Y x Co 3 are calculated from a statistical distribution of Gd-ions in a mean-field approximation. The Gd subsystem is considered magnetically localized, whereas the magnetic properties of Co are described through a density of states model, built from the experimental M vs . H curve of YCo 3. We measured magnetization curves for x=0.0,0.2,0.4,0.78, and compared to theoretical results. Excellent agreement between the theory and experimental data was obtained.
