摘要：

CoPt alloy films with large perpendicular magnetic anisotropy, perpendicular coercivity, and saturated perpendicular remanence are reported. These films were fabricated by e-beam evaporation at substrate temperatures near 200-degrees-C and above. Well-(111)-textured Pt underlayers are shown to dramatically increase the perpendicular magnetic anisotropy of CoPt alloy films. The large perpendicular magnetic anisotropy is shown to be strongly related to good CoPt (111) texture, and not to the ordered tetragonal Co50Pt50 phase.
