Abstract

A magnetoresistive element includes a first magnetic layer; and laminations of a second magnetic layer, a non-magnetic layer and a third magnetic layer. The laminations are adjacent to the first magnetic layer. The second magnetic layer and the third magnetic layer have different coercive forces, wherein the first magnetic layer is selected from CoCrTa, NdFe, and alloys thereof.
