FePt L1 sub(0) ordering and grain growth using millisecond pulse laser processing
The structural and magnetic properties of [inline image]12 nm thick FePt thin films grown on Si substrates annealed using a 1064 nm wavelength laser with a 10 ms pulse have been examined. The A1 to L1 sub(0) ordering phase transformation was confirmed by electron and X-ray diffraction. An order para...

| description | The structural and magnetic properties of [inline image]12 nm thick FePt thin films grown on Si substrates annealed using a 1064 nm wavelength laser with a 10 ms pulse have been examined. The A1 to L1 sub(0) ordering phase transformation was confirmed by electron and X-ray diffraction. An order parameter near 50% and a maximum coercivity of 12 kOe were obtained with laser energy densities of 25-32 J/cm super(2). Grain growth, quantified by dark field transmission electron microscopy, occurred during chemical ordering at the laser pulse widths studied. |
