Abstract
Good magnetic, wear, and corrosion properties are required of a pinned synthetic anti-ferromagnet used in a top spin valve magnetoresistive sensor for reading magnetic media. The pinned synthetic anti-ferromagnet includes a synthetic anti-ferromagnet. An oxidation protection layer is deposited on the synthetic anti-ferromagnet. A nickel oxide layer for pinning the synthetic anti-ferromagnet is deposited on the oxidation layer.
