SOFT MAGNETIC MATERIAL, DUST CORE, PROCESS FOR PRODUCING SOFT MAGNETIC MATERIAL, AND PROCESS FOR PRODUCING DUST CORE |
摘要 |
A soft magnetic material includes a plurality of composite magnetic particles (40) each including a metal magnetic particle (10) and an insulation coating (20) covering the surface of the metal magnetic particle (10), wherein the insulation coating (20) contains Si (silicon), and 80% or more of Si contained in the insulation coating constitutes a silsesquioxane skeleton. Therefore, it is possible to effectively decrease a hysteresis loss while suppressing an increase in eddy-current loss. |
