Abstract:
A magnetic metallic glass alloy that is at least about 70% glassy, has been annealed to enhance magnetic properties, and has a composition consisting essentially of the formula Fe.sub.a Co.sub.b Ni.sub.c M.sub.d B.sub.e Si.sub.f C.sub.g, where M is at least one member selected from the group consisting of molybdenum, chromium and manganese, ""a"", ""b"", ""c"", ""d"", ""e"", ""f"" and ""g"" are in atom percent, ""a"" ranges from about 19 to about 29, ""b"" ranges from about 16 to about 42 and ""c"" ranges from about 20 to about 40, ""d"" ranges from about 0 to about 3, ""e"" ranges from about 10 to about 20, ""f"" ranges from about 0 to about 9 and ""g"" ranges from about 0 to about 3, said alloy having the form of a strip that exhibits mechanical resonance and has a substantially linear magnetization behavior up to a minimum applied field of about 8 Oe.
