Succinatw-Citrate 계 무전해 도금에 의한 수직자기 박막의 자성특성

Magnetic Properties of a Perpendicular Magntic Film Made Electroless Plating a Succining Bath

An electroless plating both for normal orientation of HCP-structure of Co-P to the film plane was developed. An ammonical succinate-citrate bath containg MnSo4, NiSO4 was studied Ni was codeposited into the films in order to decrease the saturation magentization (MS) since low Ms is necessary to decrease the magentizing fild. Mn was also codeposited to increase perpendicular orentaon of Co-P film. Effects on film composition and magnetic properties were studid in connection with follwing four factors such as concentration of NiSo4 and MnSo4, bath temp and pH.
