英文摘要: Abstract(#br)Among different magnetic thin films, L 1 0 FePt due to high magnetocrystalline anisotropy is attracting much attention for applications in new generation of magnetic recording media. In this work, switching time and switching mechanism of magnetization as essential properties of L 1 0 FePt film was studied by magneto-optical Kerr effect (MOKE) and time-resolved magneto-optical Kerr effect (TR-MOKE). For this purpose, static in plane and out of plane magnetic hysteresis loop of the 20-nm thick L 1 0 FePt film on (1 0 0) MgO was measured and modeled using polar and longitudinal MOKE and mumax code, respectively. Furthermore, the switching time of magnetization was studied using laser-induced ultrafast demagnetization and relaxation of the sample by TR-MOKE, in which for the...
