Microstructure and Magnetic Properties of FePt/Ag Nanocomposite Films with Perpendicular Orientation

Abstract:

Article Preview

[FePt(2 nm)/Ag(d nm)]10 mutilayers were deposited on single crystal MgO (100) substrates by magnetron sputtering. L10-FePt/Ag nanocomposite films with a high coercivity and a perpendicular orientation were achieved by annealing the as-deposited films at 600 °C for 15 min. The result of high resolution transmitting electron microscopy (HRTEM) shows apparent mutilayer structure of the [FePt(2 nm)/Ag(5 nm)]10 film. We also found the good epitaxial growth of FePt on MgO [001] direction. Atomic force microscopy (AFM) observation on the surface morphology showed that the surface particle size and roughness degree decrease with increasing the Ag layer thickness.
