The combination of high magnetocrystalline anisotropy
energy density and good corrosion resistance, the
latter when compared with rare-earth based alloys,
has resulted in significant interest in L10 ordered
alloys such as FePt and CoPt for ultrahigh density,
heat assisted magnetic recording (HAMR) media.
However, when deposited at room temperature, these
alloys form in the chemically-disordered A1 state,
requiring a post-deposition anneal to form the
ordered L10 phase. The objective of this project
is to study the impact of ternary alloying additions
on the kinetics and thermodynamics of the formation
of the ordered L10 phase from the A1 state. |
