Abstract :
Ribbons of amorphous RE65Al35alloys (where RE = Ce, Pr and Dy) were prepared by melt spinning under vacuum. Magnetization measurements, carried out on a vibrating sample magnetometer with magnetic fields H \\leq 20 kOe and over a temperature range 2.8°K \\leq T \\leq 300 °K, are reported here. Dy65Al35and Pr65Al35demonstrated a ferromagnetic-like ordering which was characterized by the appearence of a cusp at 30 °K and 7 °K, respectively. In both cases, hysteresis and relaxation effects occurred below the ordering temperature. Amorphous Ce65Al35exhibited a negative paramagnetic Curie temperature of -40 °K, but did not order for temperatures down to 2.8 °K. The results are discussed in terms of the random atomic arrangement and its influence on the exchange and anisotropy interactions.
