摘要
A free layer for a spin valve sensor includes a cobalt iron (CoFe) film which has an easy axis oriented perpendicular to an air bearing surface (ABS) of a read head and a nickel iron (NiFe) film which has an easy axis oriented parallel to the ABS and parallel to the major planes of the thin film layers. In a further embodiment the free layer is annealed at a high temperature in the presence of a field which is oriented perpendicular to the ABS.
