Abstract
The authors developed the electrodeposition technique for CoPt thin films applicable to 3-D domain wall motion memory (3D-DWMM). CoPt films with perpendicular magnetic anisotropy (PMA) were obtained in a wide range of the Co composition which was controlled by adjusting the potential during electrodeposition. The magnetic properties of the CoPt films were controlled via the Co composition. The pulse electrodeposition method was conducted to obtain smooth morphology of the Co68Pt32 films. Ultra-thin Co68Pt32 films with smooth surface morphology and an excellent squareness ratio were obtained. This study promises the electrodeposition of the artificial ferromagnetic multilayers for the magnetic pillar of the 3-D-DWMM can be achieved.
