| 摘要 |
A cobalt based, manganese-containing glassy metal alloy is provided. The alloy has a combination of near-zero magnetostriction (+5 ppm to -1 ppm), high permeability (greater than 5,000) and high saturation induction (about 1.09 T or greater). The alloy has a composition described by the formula [CoaFe1-a]100-(b+c) MnbBc-dSid, where "a" ranges from about 0.90 to 0.99, "b" ranges from about 2 to 6 atom percent, "c" ranges from about 14 to 20 atom percent and "d" ranges from zero to about 7 atom percent, with the proviso that the minimum B present is 10 atom percent. The alloys of the invention find use in magnetic recording heads, switching power supplies, special magnetic amplifiers and the like. |
