Abstract

A high-saturation magnetization composite soft magnetic film can be deposited by magnetron co-sputtering of two or more kinds of materials using targets which have a lower saturation magnetization than that of a single target, which otherwise will be used to produce the resulting composite soft magnetic film. The composite film has a substantially uniform composition and thickness.
