Title: Thin-film electrode layer including .beta.-ta and thin-film magnetic head using the same

Abstract: A thin-film electrode layer having a superior electromigration resistance is disclosed. The thin-film electrode layer includes a first base layer composed of .beta.-Ta, a main conductive layer composed of Au, and a protective layer. The protective layer is a composite of a Cr sublayer and an .alpha.-Ta sublayer. A thin-film magnetic head having the thin-film electrode layers and a method for forming electrodes in the thin-film magnetic head are also disclosed.
