Perpendicular magnetic anisotropy in the Co_(50)Pt_(50), Co_(50)Pd_(50), and Co_(50)Pt_(50 - x)Pd_x thin films

摘要

Films of the Co_(50)Pt_(50), Co_(50)Pd_(50), and Co_(50)Pt_(50 - x)Pd_x alloys (where x = 1-10 at %) have been prepared. The processes of atomic ordering and its influence on the perpendicular magnetic anisotropy and the coercive force in these films have been investigated. The dependence of the coercive force on the film thickness has been analyzed. It has been shown that thin films of ordered alloys become magnetically uniaxial with the easy axis normal to their plane and can be used for magnetic and thermomagnetic recording and storage of information.
