摘要：
By making use of the dc magnetron sputtering system, the Au/FePt bilayers have been prepared on glass substrates and anodized aluminum oxide (AAO) membranes with an average pore diameter of around 200 nm. In both cases, the FePt films can be converted into the magnetically hard phase, namely L1(0) phase, after a heat treatment above 500 degrees C for 1 h. A nanoparticle-like structure can be observed in the 15-nm-thick FePt film on the AAO membrane. The experimental observations of the structure and the magnetism of the FePt films on the AAO membranes are firstly established. (C) 2010 Elsevier Ltd. All rights reserved.
