At room temperature, perpendicularly ordered L10FePt thin film exhibits extremely high uniaxial anisotropy with easy axis oriented along the ordering direction [1]. The relatively low curie temperature and high temperature gradient of the anisotropy field near the Curie point of the L10 FePt makes it almost perfect as a recording media for heat assisted magnetic recording (HAMR) technology [2-5].
