摘要：
Microstructure variation of FePt thin film upon annealing at elevated temperatures was investigated by transmission electron microscopy (TEM). A special shape aperture was employed to observe the ordered L1(0) phase in the dark-field TEM images. With increasing the annealing temperature, crystal grains formed clusters with gathering of neighboring grains, and crystal grain growth proceeded within the cluster. L1(0) ordered crystal grains were preferentially formed near the grain boundaries, and their sizes grew with increasing the annealing temperature. (C) 2008 Elsevier B. V. All rights reserved.
