Effect of multilayer configuration of [Fe/Pt] multilayer to attain (001) oriented FePt ordered alloy thin films
L 1 0 -FePt ordered alloy thin films with (001) preferential orientation were fabricated from [ Pt ( 1 nm ) / Fe ( 1 nm ) ] 3 /Pt(3 nm)/Fe(3 nm) multilayers to reduce the ordering temperature. Pt(3 nm)/Fe(3 nm) layer beneath the [ Pt ( 1 nm ) / Fe ( 1 nm ) ] 3 multilayer played a role as a s...
