Dependence of Magnetic Damping on Temperature and Crystal Orientation in Epitaxial Fe4N Thin Films
2014
Journal of the Magnetics Society of Japan
In-plane and out-of-plane ferromagnetic resonance (FMR) were used to investigate the intrinsic magnetic damping constant () in epitaxial Fe4N thin films deposited on MgO substrates. The dependence of on temperature was evaluated from room temperature (RT) to 4 K. The external magnetic field (H) of FMR was applied in two directions, i.e., [100] and [110], of the Fe4N lattice. Anisotropic was observed from RT to 4 K. Moreover, the for H // [100] exceeded the for H // [110] at 180 K.
