- 論文の詳細を見る
CoFe soft magnetic thin films with high saturation magnetic flux density B_s were prepared by electrodeposition. The B_s value of CoFe alloy films prepared by direct-current electrodeposition is as high as that of bulk alloys with 24kG, however, the coercivity H_c values are higher than 12 Oe. The application of pulsed electrodeposition, especially pulse-reverse electrodeposition, resulted in the decrease of H_c to approximately 1 Oe. It is suggested that decreasing H_c of the films by pulse-reverse electrodeposition is caused by relaxation of film stress and smoothing of surface morphology.
