Abstract (en)
[origin: EP2219195A1] The present invention relates to a soft-magnetic composite material obtained by compaction and heat treatment. This material is produced by mixing and compacting Mg-containing oxide-coated soft-magnetic particles with at least one type of silicone resin, low melting glass and metal oxide, and heat treatment in a non-oxidizing atmosphere to obtain a precursor of a soft-magnetic composite compaction-heat treated material, followed by heat-treating in an oxidizing atmosphere to obtain a heat treated body.
