Abstract
- A near-equiatomic FePt face-centered-cubic alloy has been grown by electrodeposition onto Cu(001). Annealing at 450 °C results in the onset of a A1 fcc to L10 face-centered-tetragonal phase transformation with a dominant FePt(001)<100>∥Cu(001)<100> recrystallization texture, possibly driven by the reduced ordering temperature in an FePtCu intermixed interface region. Further annealing at 650 °C leads to a more complete transformation, and magnetic measurements indicate that high perpendicular coercivities, of 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-density patterned perpendicular magnetic media.
