Abstract
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 mR are obtained in samples with very fine Nd2Fe14B-type grains having a size of about 180 Å. 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.This publication has 7 references indexed in Scilit:
