PROBLEM TO BE SOLVED : To provide a thin-film magnet capable of achieving high magnetic performance, i.e., a high maximum energy product. SOLUTION : In order to achieve the thin-film magnet having a high maximum energy product, there is provided a configuration of the thin-film magnet which is capable of achieving high magnetic anisotropic energy and high saturation magnetization. One or more metals selected from a group consisting of Ta, Nb, V, Cr, Ru, Cu, and Ag are formed directly on one surface of an Fe or FeCo film. A ferromagnetic material containing a rare earth element is formed directly on the other surface of the Fe or FeCo film. COPYRIGHT : (C)2013, JPO&INPIT
