Deposition of Co/Pt film with perpendicular magnetic anisotropy by layer stacking sputtering
Taruho Tsuchiya, Naoki Honda (Tohoku Inst. Tech.)
Abstract (in Japanese) (See Japanese page) 
(in English) Low temperature preparation of Co/Pt stacked film with high magnetic anisotropy was studied using atomic layer stacking collimated sputter-deposition. Although a trace super lattice line corresponding to the L11 ordered phase was observed for films with higher Ar pressure and higher substrate temperature deposition in the X-ray diffraction, L11 ordering was not supposed to be obtained. Magnetic properties, however, exhibited a high saturation magnetization of about 1000 emu/cm3 and a large perpendicular magnetic anisotropy. Low Ar pressure sputtering at 0.8 Pa exhibited little difference in magnetic properties between films deposited at different substrate temperatures. On the contrary, the films deposited at a high Ar pressure of 9.6 Pa exhibited a high coercivity of 5 kOe for RT deposition, but the coercivity decreased and the anisotropy field was increased to be estimated as high as about 20 kOe, which indicated a high perpendicular anisotropy of 1×107 erg/cm3. The cause of the anisotropy was suggested to be come from micro ordering.
