Exchange coupling film having improved wettability of seed layer
A seed layer is formed of a Cr film with a thickness of 15 Å or more and 50 Å or less comprising at least partially an amorphous phase, thereby enabling wettability of the surface the seed layer to be remarkably improved as compared with conventional one, the unidirectional bias magnetic field in the pinned magnetic layer to be increased, and the surface of each layer on the seed layer to have good lubricity.
