Abstract

An amorphous metal alloy which is at least 90% amorphous having enhanced magnetic properties and consisting essentially of a composition having the formula FeaSibBc wherein "a", "b" and "c" are atomic percentages ranging from about 75 to 78.5, 4 to 10.5 and 11 to 21, respectively, with the proviso that the sum of "a", "b" and "c" equals 100.
