摘要：
The magnetization and ac-susceptibility of liquid quenched R(3)Co (R = Nd, Tb, Dy) alloys were determined. The magnetic ordering temperatures T-c of the alloys are about 30, 84 and 38 K, respectively. Their magnetic state below T-c can be associated with an asperomagnetic structure. The alloys show large hysteresis loops at low temperature. The coercive field (H-c) depends on the T-c value and increases with increasing T-c. Large discontinuous magnetization jumps were observed for Tb3Co in the vicinity of H-c below 3.5 K.
