A MR multi-layered structure or a thin-film magnetic head with the MR multi-layered structure includes a non-magnetic electrically conductive material layer, first and second ferromagnetic material layer separated by the non-magnetic electrically conductive material layer, and an anti-ferromagnetic material layer formed adjacent to and in physical contact with one surface of the second ferromagnetic material layer, the one surface being in opposite side of the non-magnetic electrically conductive material layer. The second ferromagnetic material layer includes a first layer of a ferromagnetic material containing Co, and a second layer of a ferromagnetic material with a smaller magnetic anisotropy than that of Co.
