Abstract
The structural and magnetic properties of â¼12Â nm thick FePt thin films grown on Si substrates annealed using a 1064Â nm wavelength laser with a 10Â ms pulse have been examined. The A1 to L10 ordering phase transformation was confirmed by electron and X-ray diffraction. An order parameter near 50% and a maximum coercivity of 12Â kOe were obtained with laser energy densities of 25-32Â J/cm2. Grain growth, quantified by dark field transmission electron microscopy, occurred during chemical ordering at the laser pulse widths studied.
