An amorphous phase was formed after quenching by melt spinning with a copper wheel with a surface speed of 30 m/s. The magnetic properties of the ribbons were measured by vibrating sample magnetometer. The Curie temperature increases with increasing Y concentration (x = 0 to 10). Temperature dependence of the entropy variation Delta S-M was calculated from the isothermal magnetization. The maximum of Delta S-M was found to appear in the vicinity of the Curie temperature of the amorphous phase. Their values are 1.22, 0.89 and 1.12 J/kg K at x = 0, 5 and 10, respectively.
