Abstract
PURPOSE: To obtain a thin-stripped amorphous magnetic material with a raised crystallization temp. and low magnetostriction for a magnetic head, etc. by adding a rare earth metal to an Fe-Co-Si-B alloy having a specified atomic ratio and by rapidly cooling the resulting alloy in a specified atmosphere.
CONSTITUTION: This amorphous magnetic material consists of, by atom, 0.1W 12% Fe, 36W24% Si, 1.8W22% B, 0.3W5% of ≥1 kind of rare earth metal selected from Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb, and the balance Co. The material may further contain ≤16% Ni. The material is manufactured by very rapid cooling in a vacuum or an inert gaseous atmosphere, and it is represented by a chemical formula[(Fe1-aCoa)1-gREg]100-x(SizB1-z)x, wherein 0.85≤a≤0.99, 0.005≤g≤0.06, 18≤x≤26, and 0.2≤z≤0.9. This amorphous magnetic material has about 450W750°C crystallization temp. and ≤ about 3× 10-6 magnetostriction constant.
