Abstract
Disclosed is a Fe—Ga—P—C—B—Si based metallic glass alloy particle prepared by a gas atomizing process, which has an approximately complete spherical shape, a relatively large particle size and a high crystallization temperature (Tx). The plurality of particles may be subjected to a spark plasma sintering process at the crystallization temperature or less under a compression pressure of 200 MPa or more, to provide a bulk Fe-based sintered metal soft magnetic material of metallic glass, which has a high density, a single phase structure of metallic glass in an as-sintered state, excellent soft magnetic characteristics applicable to a core of a magnetic head, a transformer or a motor, and a high specific resistance.
