Description
The large values of remanence observed in isotropic melt-spun R-Fe-Al-B-Si samples have been investigated by correlating the magnetic properties with the microstructure. Transmission electron microscope studies showed that the highest values of reduced remanence m/sub R/ are obtained in samples with very fine Nd2Fe14B-type grains having a size of about 180 A. The increased reduced remanence can be explained by the large interaction among the magnetic moments of neighboring grains which is caused by the large surface-to-volume ratio of the fine grains
