摘要: Magnetization reversal processes in sintered and melt-quenched NdFeB materials have been investigated by measurements of reversible magnetization. For isotropic anisotropic hot pressed die upset (MQIII) magnetization is the result bowing pinned domain boundary walls. In contrast melt quenched (MQI) appears to be rotation vectors not wall bowing. The differences four are determined.
