Thin film of Ni-Co-Fe ternary alloy and process for producing the same
 A magnetic thin film of Ni-Co-Fe ternary alloy containing at most 75% by weight of Ni, 10 to 90% by weight of Co, and at most 15% by weight of Fe, which shows the magnetostriction constant between +2.times.10.sup.-6 to -2.times.10.sup.-6 and shows a uniaxial magnetic anisotropy of at most 10 Oe. The film is formed through the vacuum evaporation of the alloy during which two orthogonal external magnetic fields, directions x and y, are alternately applied over the deposition surface of a substrate. The film is suitable for a core material of a thin film magnetic head with a higher recording density.
