The structural transformation from fcc to fct and relevant magnetic pr
operties of initially multilayered Fe/Pt films were studied. When the
as-deposited Fe/Pt films were annealed at the temperature of 300 degre
es C and up, the fct-phase was formed. Rather square hysteresis loops
and large coercivities were measured from the annealed films. The film
s annealed at 300 degrees C retain a layered structure.
