Abstract: The magnetic properties of films of binary systems R$_x$T$_{100-x}$ ($R$ = Y, La, Gd; $T$ = Co, Ni) obtained by magnetron sputtering in a range enriched in 3$d$ metals ($x<$ 50) have been studied. The concentration and temperature dependences of spontaneous magnetization, Curie temperature, and average magnetic moment per transition metal atom are obtained. The differences in the magnetism of $R$–$T$ systems containing different 3$d$-elements are interpreted.

Keywords: thin films, rare earth metals, transition metals, magnetic moment, ferrimagnetism.
