Title: Magnetoresistive shield incorporating seedlayer for anisotropy enhancement

Abstract: A layer of iron--silicon--aluminum alloy is deposited over a seedlayer of an amorphous alloy to form a shield for a read element in a recording head. Percentage weights of iron, silicon, and aluminum in the iron--silicon--aluminum alloy are each selected such that the alloy has both near-zero magnetostriction and distinct magnetocrystalline anisotropy. Use of the amorphous alloy seedlayer results in greater magnetocrystalline anisotropy in the shield.
