<p>In the present invention, used is a magnetic material which contains Fe-based particles (3) which containα-Fe orα-(Fe,Co), anεphase (2) which containsε-Fe2O3 orε-(Fe,Co)2O3, and an aluminum-containing silicon oxide (1) or the like. The Fe-based particles (3) have boundaries that come into contact with theεphase (2) and the aluminum-containing silicon oxide (1) or the like. Due to this configuration, by using a material that does not contain a rare earth element, it is possible to obtain a magnetic material in which inflection points on a demagnetization curve are eliminated without causing a reduction in coercive force.</p> |
