The single-layered Fe-Pt films with thickness of 30 nm are in-situ deposited directly on Si substrate at various substrate temperatures (T-s) of 350 to 590 degrees C. As the Fe-Pt film is sputtered at substrate temperature is 350 degrees C, it shows (111) preferred orientation and tends to in-plane magnetic anisotropy. The L1(0) Fe-Pt film with (001) texture is obtained and exhibited perpendicular magnetic anisotropy as the substrate temperature is increased to 470 degrees C. The perpendicular coercivity (Hc(perpendicular to)) saturation magnetization (Ms) and perpendicular squareness (S-perpendicular to) of this film are 6.9 kOe, 674 emu/cm(3) and 0.89, respectively, which reveal its significant potential as perpendicular magnetic recording media.
