Abstract
A base multilayer body is made by laminating a seed layer and a buffer layer in respective order. The seed layer is an alloy layer containing tantalum (Ta) and at least one type of other metal, and having an amorphous structure or a microcrystal structure. The buffer layer is an alloy layer having a [001] plane orientation hexagonal close-packed structure and containing at least one type of a group VI metal and at least one type of a group IX metal in the periodic table. With this configuration, a magnetic layer providing a desired magnetic characteristic(s) can be laminated on the thinned base multilayer body.
