PURPOSE:To produce a soft magnetic alloy having high Bs, low Hc and high muand in which deterioration in Hc and mu are small by constituting it of a compsn. contg. specified atomic ratios of Fe, Co and Ni as essential components and specifying the ratio of the peak intensity between specified faces. CONSTITUTION:The essential components of this soft magnetic alloy are constituted of Fe, Co and Ni. In the formula of FexCoyNiz, the atomic ratio of each element in these essential components is expressed by 0.10<=x<=0.55, 0.20<=y<=0.85, 0.05<=z0.35 and x+y+z=1. The, the soft magnetic alloy is substantially constituted of a face-centered cubic crystal single phase. In the case the peak intensity of the (200) plane and that of the (111) plane in the X-ray analysis are respectively defined as I(200) and I(111), I(200)/I(111)>=0.25 is regulated. Furthermore, the absolute value of the saturation magnetostriction value (lambdas) is regulated to 5X10<-6> or below. In this way, the lambdas can substantially be regulated to zero even in the compositional range by which high Bs can be obtd. |
