ABSTRACT:
A seed layer is formed with a Cr layer in which the direction of a crystal face in at least one crystal grain is oriented in a different direction from the direction of an equivalent crystal face in another crystal grain. Consequently, wettability of the seed layer can be markedly improved and the unidirectional exchange bias magnetic field in a pinned magnetic layer can be increased while permitting the surface of each layer on the seed layer to have good lubricity.
