PROBLEM TO BE SOLVED: To provide a method for improving the magnetic properties of a metal glass alloy having excellent linear B-H loops with low core losses. SOLUTION: A metallic glass alloy strip consists essentially of about 70 to 87 atom% iron. Up to about 20 atom% of the iron is replaced by cobalt and up to about 3 atom% of the iron is replaced by nickel, manganese, vanadium, titanium or molybdenum. About 13 to 30 atom% of the element balance includes members selected from the group consisting of boron, silicon and carbon. The alloy is heat-treated at a sufficient temperature to achieve stress relief. A magnetic field applied during the heat-treatment causes the magnetization to point away from the strip's predetermined easy magnetization direction. The metallic glass exhibits linear DCBH loops with low ac losses. As such they are especially well suited for use in current/voltage transformers. COPYRIGHT: (C)2011,JPO&INPIT
