Abstract:
A magnetoresistive effect multi-layered structure, comprising:a non-magnetic electrically conductive material layer; first and second ferromagnetic material layers separated by said non-magnetic electrically conductive material layer; and an anti-ferromagnetic material layer formed adjacent to and in physical contact with one surface of said second ferromagnetic material layer, said one surface being located on a side opposite of said non-magnetic electrically conductive material layer, said second ferromagnetic material layer including a first non-amorphous layer made of Co, said first non-amorphous layer being stacked on said non-magnetic electrically conductive material layer, and a second layer of a ferromagnetic material with a smaller magnetic anisotropy than that of Co, said second layer being stacked on said first non-amorphous layer.
