PURPOSE: To provide a magnetic thin film, whose coercive force and magnetostriction constant are both small and which is capable of stably obtaining high saturation magnetization of 18,000 to 23,000 G, a method of manufacturing the same, a magnetic head using the same, and an electroplating apparatus. CONSTITUTION: The ratio of the diffracted X-ray intensity fcc (200) on the face-centered cubic lattice (200) plane of a magnetic thin film of Co-Ni-Fe alloy to the diffracted X-ray intensity fcc (111) on the face-centered cubic lattice (111) plane of the thin film is represented by fcc (200)/fcc (111), and the ratio fcc (200)/fcc (111) is set smaller than 0.25. Also the peak intensity ratio of the intensity bcc (110) of the diffracted X-ray on the face-centered cubic lattice (110) plane to that of the intensity fcc (111) of diffracted X-ray on the face- centered cubic lattice (111) plane is set at 0.01 to 3.0.
