摘要

采用二元合金法制备了不同晶粒尺寸和矫顽力的烧结磁体。大块磁铁被切成小块，有些用硝酸溶液蚀刻，然后进行热处理和老化。磁性能是用振动样品磁强计测量的。晶粒尺寸分布的测量使用光学图像从烧结磁铁研磨和蚀刻后的Villela的试剂。

Magnetic properties of extremely small Nd-Fe-B sintered magnet

Sintered magnets with various grain sizes and coercivities were prepared by the binary alloys method. Bulk magnets are cut into small pieces, some are etched by a nitric acid solution and heat treated and subjected to aging. Magnetic properties are measured by vibrating sample magnetometer. Grain size distributions are measured using optical images taken from the sintered magnets after lapping and etching by the Villela's reagent.
