Abstract
A magnetic laminated film used for a magnetic transducer is constructed in such a way that a ferromagnetic film as a ferromagnetic body is made of, for example, a Ni--Fe alloy film, formed on a substrate made of, for example, glass, and an antiferromagnetic film as an antiferromagnetic body having crystal structure of body-centered cubic lattice, for example, made of a Cr alloy film is laminated on the top layer. Further, a magnetic transducer using the magnetic laminated film is applied to a magnetic head in a magnetic recording device in accordance with the present invention.
