Abstract

Provided is a sputtering target or a film which is characterized by containing 0.1 to 10 mol % of an oxide of one or more types selected from FeO, FeO, KO, NaO, PbO, and ZnO, 5 to 70 mol % of Pt, and the remainder being Fe. The present invention addresses the issue of providing a sputtering target capable of considerably reducing the particles caused by nonmagnetic materials and significantly improving the yield during deposition. It is thereby possible to deposit a quality magnetic recording layer and improve yield of a magnetic recording medium.
