MAGNETIC CORE FOR HIGH FREQUENCY AND INDUCTIVE COMPONENT USING SAME

摘要

A magnetic core for high frequency is disclosed which is a formed body of a mixture wherein not more than 10%, in mass ratio, of a binder is blended in a soft magnetic metal glass powder which has a composition represented by the general formula: (Fe1-a-bNiaCob)100-x-y-z(M1-pM'p)xTyBz (provided that 0 <= a <= 0.30, 0 <= b <= 0.50, 0 <= a + b <= 0.50, 0 <= p <= 0.5, 1 atom% <= x <= 5 atom%, 1 atom% <= y <= 12 atom%, 12 atom% <= z <= 25 atom%, 22 <= (x + y + z) <= 32, M is at least one element selected from Zr, Nb, Ta, Hf, Mo, Ti, V, Cr and W, M' is at least one element selected from Zn, Sn and R (R are rare earth metals including Y), and T is at least one element selected from Al, Si, C and P). Also disclosed is an inductive component which is formed by winding a coil wire around such a magnetic core for high frequency at least one turn.
