“…On the other hand, the dynamic magnetic properties such as magnetic anisotropy and magnetization damping of Zn x Fe 3x O 4 thin films are less reported may be related to the difficulty of the ultrafast dynamic characterization. Fe 3 O 4 thin film has large Gilbert damping and weak magnetic anisotropy in nature [10,11]. Zn dopant in Zn x Fe 3x O 4 thin film can induce extrinsic damping and additional magnetic anisotropy.…”

The strong (111)-textured Zn x Fe 3x O 4 thin films were grown on SiO 2 -terminated silicon substrates using pulsed laser deposition. X-ray diffraction and high resolution transmission electron microscopy clearly show the column growth structure along the film thickness direction in [111] crystalline orientation for every grain column. With the introduction of texture induced magnetic anisotropy in the free energy density model, we quantitatively determined the doping effect on the various anisotropies in (111)-textured Zn x Fe 3x O 4 films. The mechanisms of ferromagnetic resonance linewidth of Zn x Fe 3x O 4 thin films are investigated by the theoretical fitting, in which considering the contributions from intrinsic spin-orbit coupling, extrinsic compositions from two-magnon scattering and inhomogeneous broadening. It is found that the Gilbert damping coefficient  increases with increasing Zn substitution x from 0 to 0.3, indicating that the spin-orbit coupling of the Zn x Fe 3x O 4 thin films increases with the introduction of Zn impurities.
