Fe-Pt films were electrodeposited from an alkaline electrolyte containing Fe as a citrate complex and Pt as an amino-nitrite Up to 6 at % oxygen was present in as-deposited films much lower than the 30 at % value reported for Fe-Pt films deposited from weakly complexing acidic electrolytes Pt-rich films exhibit a face-centered cubic structure nearly equiatomic films are transformed to the stable tetragonal structure by thermal annealing between 400 and 700 C in forming gas In films with thickness ranging from 13 to 93 nm phase transformation occurs at lower temperatures in thicker films 93 nm thick films exhibit a coercivity of 13 kOe after annealing at 450 C a temperature much lower than that required to achieve full magnetic hardening when growing from weakly complexing acidic solutions (C) 2010 Elsevier Ltd All rights reserved
