Microstructure of electrodeposited Fe–Pt binary alloy films

Fe–Pt alloy films were electrodeposited in a novel bath containing ammonia solution and ammonium tartrate as complexing agent. The compositions of the Fe–Pt deposited films were controlled by bath composition and current density. The crystallographic structures of deposited films with compositions ranging from 34.0 at.% Pt to 81.8 at.% Pt were analysed by means of XRD, HRTEM and ESCA. The crystallographic structure of all the deposited films, which were obtained in the present study, consisted of a single solid solution of a face-centred cubic structure.
