Abstract:
A magnetic powder is represented by general formula FeaSibBcPdCue. 71.0≤a≤81.0, 0.14≤b/c≤5, 0≤d≤14, 0<e≤1.4, d≤0.8a−50, e<−0.1(a+d)+10, and a+b+c+d+e=100. A crystallinity is not more than 30% in the case of containing an amorphous phase and a compound phase, and is not more than 60% in the case of not containing a compound phase. The magnetic powder is produced with a gas atomization method. Whereby, it is possible to obtain an alloy magnetic material which has high saturation magnetic flux density and low magnetic loss; and a magnetic core, coil components, and a motor can be realized.
