Abstract :
The influence of the addition of Cu in the YCo5 matrix, YCo5-xCux with 0⩽x⩽3, on magnetic and structural properties was investigated. With increasing Cu concentration a decreasing saturation magnetization, anisotropy energy and Curie temperature were obtained. Contrary to the results obtained in Sm(Co,Cu) 5 alloys neither an enhancement of the coercive force nor a dH/dt dependence of the coercive force was found. The temperature dependencies of both the saturation magnetization and magnetic anisotropy constant K1 for YCo3Cu2 were analyzed using the spin-wave and Yang model, respectively
