Abstract
An amorphous metal alloy which is at least 90 percent amorphous and consists essentially of a composition having the formula Fe.sub.a B.sub.b Si.sub.c C.sub.d wherein 'a', 'b', 'c' and 'd' are atomic percentages ranging from about 80.0 to 82.0, 12.5 to 14.5, 2.5 to 5.0 and 1.5 to 2.5, respectively, with the proviso that the sum of 'a', 'b', 'c' and 'd' equals 100, is annealed at a temperature ranging from 380.degree.-410.degree. C. The resulting alloy has decreased high frequency core losses and increased low field permeability; is particularly suited for high frequency applications.
