Abstract:
1. A magneto-resistive effect element, said magneto-resistive effect element being a giant magneto-resistive element including a lamination layer structure portion in which at least a free layer the magnetization of which is rotated in response to an external magnetic field, a fixed layer, an antiferromagnetic layer for fixing the magnetization of said fixed layer and a nonmagnetic layer interposed between said free layer and said fixed layer are laminated and in which a sense current flows to substantially a lamination layer direction of said lamination layer structure portion, wherein said lamination layer structure portion has disposed thereon a high-resistance layer which crosses a path of said sense current, wherein said high-resistance layer is disposed at not less than any one of the inside of said free layer, the surface of said free layer as is opposite to a surface at which it is bonded to said nonmagnetic layer, the inside of said ferromagnetic layer comprising said fixed layer, the inside of said antiferromagnetic layer, and the surface of said antiferromagnetic layer as is opposite to a surface at which it is bonded to said fixed layer.
