MAGNETIC IRON OXIDE PARTICLE, MAGNETIC MATERIAL, AND RADIO WAVE ABSORBER |
摘要 |
<p>Disclosed is a magnetic material having high Hc and and High Curie point, which is capable of controlling such magnetic characteristics without requiring rare or expensive raw materials. Specifically disclosed is a magnetic material composed of particles of a magnetic iron oxide which is represented by the following general formula: µ-A x B y Fe 2-x-y O 3 or µ-A x B y C z Fe 2-x-y-z O 3 (wherein A, B and C each represents a metal excluding Fe and different from each other, satisfying 0 < x, y, z < 1), with µ-Fe 2 O 3 as a main phase.</p> |
