Structure and Properties of Electrodeposited FePt Films
Fe-Pt binary alloy thin films were fabricated through a pluse electrodeposition in a novel bath with a simple composition on copper substrates. Composition, morphology and structure of electrodeposited Fe-Pt films were investigated in dependence on deposition potential. In a broad potential range from 2.0 to 6.0V, oxygen was detected in the films. Continuous Fe-Pt alloy films with controllable compositions in 16-58 atom% Fe were achieved on copper substrates. In particular, the films with a composition close to 1:1 Fe/Pt was obtained at -4.7V. All Fe-Pt films as-synthesized exhibited essential characteristics of soft magnetic and isotropic behavior, as investigated by a vibrating sample magnetometer (VSM).
