摘要: Microstructure and magnetization processes of highly ordered FePt(001) films with large perpendicular magnetic anisotropy have been studied. The film morphology was controlled from assemblies single-domain nanoparticles to those multidomain islands by varying the nominal thickness (tN) FePt sputter-deposited on a heated MgO(001) substrate. change in process rotation domain wall displacement is clearly demonstrated initial curves. Huge coercivities as high 70 105kOe achieved particles at room temperature 4.5K, respectively.
