Abstract
Magnetic crystalline grains are spaced from each other on a base layer a polycrystalline structure. The magnetic crystalline grains are made of an ordered alloy. The ordered alloy serves to ensure the crystalline magnetic anisotropy energy larger than that of Co alloy in the magnetic crystalline grains. Such crystalline magnetic anisotropy energy reaches over 1×10J/m, for example. A sufficient magnetic crystalline magnetic anisotropy energy serves to reliably maintain the magnetization in finely structured magnetic crystalline grains. The ordered alloy may have the L1structure, for example. The ordered alloy may include of FePt(atom %), FePd(atom %), CoPt(atom %), and the like.
