Abstract
A raw material for a magnet, which comprises Sm and Fe. A magnet is obtained by nitriding this raw material for a magnet. In particular, a raw material for a magnet comprises an Sm—Fe binary alloy as a main component. An intensity ratio of an SmFe(024) peak to an SmFe(110) peak is less than 0.001 as measured by an X-ray diffraction method.
