    The magnetic properties and microstructure of 25-nm-thick Co100-xPt x (x = 20~70) alloy thin films grown on glass substrate as well as on 30~150 nm Ag under layer were investigated. The Co-rich CoPt single-layer alloy thin film with hcp phase after annealing at 300°C shows large hysteresis loop and better out-of-plane magnetic properties. CoPt single-layer alloy thin film with Ll0 phase after annealing at 700°C shows better magnetic properties. For Pt-rich CoPt single-layer alloy thin film with fcc phase after annealing at 500°C shows better magnetic properties. After 300°C post vacuum annealing, the phase of Co-rich CoPt/Ag(30~150 nm) alloy thin film will change from hcp to fcc and magnetic properties become worse than Co-rich CoPt single-layer alloy thin film. After 600°C post vacuum annealing, CoPt/Ag(30~150 nm) alloy thin film sho ... 전체 초록 보기
