Subject classification: 68.55. Jk; 75.50.Ss The magnetic and structural properties of FePt and FePt-Al 2 O 3 films deposited by rf-sputtering on 7059 corning glass substrates were investigated. The coercivities of the films can be adjusted from 20 to 12.3 kOe through controlling the ordering degree
## Abstract The microstructure and magnetic properties of L1~0~ ordered Fe~55~Pt~45~ and (Fe~55~Pt~45~)~1โ__x__~โ(Al~2~O~3~)__~x~__ thin films fabricated by in situ ordering process were studied. For Fe~55~Pt~45~ thin films, preheating substrate above 250 ยฐC induces a transformation from a disorder
