Abstract :
Ultra-thin Fe-Pt films of perpendicular composite media were studied. It was found that a preparation condition at a temperature of 375°C and introduction of an exchange-decoupling layer between the Fe-Pt layer and the soft-magnetic underlayer led to reduction of the initial growth layer of the Fe-Pt film. A 5 nm thick Fe-Pt medium exhibited a high SNR and a high recording resolution with high thermal stability
