Our new paper in journal of magnetism and magnetic materials

Congratulations to our new paper ” Experimental study and micro-magnetic modeling of magnetization dynamics in L1⁠0-FePt thin film” by M. Shafei, M. M. Tehranchi, H. Falizkaran Yazdi, S. M. Hamidi, R. Yusupov, S. Nikitin

Among
different magnetic thin films, L10
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 L10 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 a L10
FePt film on (100) 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 first time, the magnetic
field was applied in the plane of the sample for this measurement.
