PURPOSE:To produce the Fe-based soft magnetic alloy particles having low coercive force by adding an element such as Nb to Fe-Si-Al-B alloy particles. CONSTITUTION:The Fe-based soft magnetic alloy particles are to be represented by a general formula of (Fe1-xMx) 100-a-b-c-dSia AlbBcM'd(where M represents Co and/or Ni and M' represents one or more elements selected from Nb, Mo, Zr, W, Ta, Hf, Ti, V, Cr, Mn, Y, Pd, Ru, Ga, Ge, C, P while x representing atomic ratio and a, b, c, d representing atomic% respectively meets the inequalities shown as follows, i.e., 0<=x<=0.5, 0<=a<=24, 1<=b<=20, 4<=c<=30, 0<=d<=10 or 0<=x<=0.15, 0<=a<=24, 2<=b<=15, 4<=c<=20, 0<=d<=10). Through these procedures, the title Fe base soft magnetic alloy particles having the least saturated magnetostriction, excellent soft magnetic characteristics and satisfactorily saturated flux density can be produced. |
