Abstract

The grain size and grain-size distribution of sputtered L10 Fe50Pt50 (300Å thick, composition in at. %) magnetic thin films on Cu (001) single-crystal substrate were investigated using high-resolution transmission electron microscopy (HRTEM). The planar TEM results showed that the grain size was about 56Å in diameter with a standard deviation of ∼10%. The cross-sectioned TEM images indicated that the magnetic grains existed in columnar structures. The L10-ordered FePt films with a small grain size and narrow grain-size distribution are potential media candidates for the high-areal density magnetic recording.
