摘要：

It is found that magnetic hysteresis in sintered magnets (Nd0.62Dy0.33Sm0.05)(16.2)(Fe0.77Co0.23)(78.1)B-5.7 for the temperature range T = 150-350 K, is caused by a mechanism associated with the displacement of domain walls, which ceases at temperatures below 150 K. In addition, the formation of magnetic hysteresis in this temperature range is affected by the mechanism involving the nucleation of the reverse magnetization phase, which is observed at temperatures down to 36 K.
