ABSTRACT:
Uniaxially oriented soft magnetic thin film consists essentially of 1 to 15 atomic percent of Co and/or Ni, and the balance being Fe, and has a crystal structure of a body-centered cubic system, wherein the film is oriented substantially in the [111] direction and the absolute value of the saturation magnetostriction .lambda..sub.f of the film is not more than 5.times.10.sup.-6. The film has low coercivity 1 Oe or less and high magnetic permeability maintaining high saturation magnetic flux density of 18 kG or more. .lambda..sub.f reaches zero and is adjustable. Addition of 0.2 to 20 atomic percent of Ru, Mn, Cr and/or V increases wear resistance. The film is formed by deposition on {111} plane of GaAs substrate, or on c-plane of hexagonal B.sub.8 stracture.
