Abstract

A near equiatomic FePt fcc alloy has been grown by electrodeposition onto Cu(001). Annealing at 450 (degrees) C results in the onset of a Al fcc to L1(subscript o) fct phase transformation with a dominant FePt(001)<100>(two vertical lines) Cu(002)<100> recrystallization texture, possibly driven by the reduced ordering temperature in an FePtCu intermixed interface region. Further annealing at 650 (degrees) C leads to a more complete transformation and magnetic measurements indicate high perpendicular coercivities, up to 10 kOe, are accessible through the recrystallization reaction. The magnetic and structural properties reported in this work may allow electrodeposited FePt to play a leading role in future ultrahigh-denisty patterned perpendicaulr magnetic media.
