Abstract
A Co—Fe—Ni magnetic film has a composition represented by a chemical formula of Co Fe Ni (50≦x≦80, 20≦y≦40, and 3≦z<10 (wt %)) and has an average grain size not greater than 40 nm. The Co—Fe—Ni magnetic film is prepared by electroplating. A magnetic head comprises the magnetic film as a magnetic pole layer. A magnetic memory device comprises a combination of the magnetic head and a magnetic recording medium having a high coercive force between 3500 and 7000 Oe, both inclusive.
