High-frequency magnetic material, producing method for the same and high-frequency magnetic device

摘要

A high-frequency magnetic material (3) includes: metal particles (1) of one of Fe and Co or alloy particles based on at least one of Fe and Co; and an oxide phase (2) containing a matrix phase and a metal oxide having a larger valence than the matrix phase. The matrix phase contains a non-reducible metal oxide and the metal oxide having a larger valence than the matrix phase forms a solid solution with the matrix phase.
