Abstract :
Summary form only given. Recently equiatomic iron-platinum alloys have attracted much attention due to their high magnetic anisotropy energy in the ordered L1/sub 0/ phase. Fe-Pt based films are considered as a promising candidate for ultra high density recording. In order to meet the requirement of the perpendicular recording, several efforts have been made to obtain perpendicular anisotropy in Fe-Pt films, which possess the in-plane easy axis in normal preparation conditions. In this paper we report a very simple method to obtain perpendicular anisotropy in Fe-Pt thin films, by Ag doping with a proper annealing.
