Magnetodynamic properties on square patterned of FeGaB and Al 2 O 3 /FeGaB thin films

This article shows low damping patterned FeGaB and Al 2 O 3 /FeGaB thin films. FeGaB has a lower damping factor (0.0071) than the Al 2 O 3 /FeGaB thin film. The coercive field and magnetic anisotropy of Al 2 O 3 /FeGaB thin films are enhanced as a result of static magnetization (Magneto-Optical Kerr Effect). The magnetic anisotropy of the Al 2 O 3 /FeGaB film produces a larger magnetic domain evolution at 10.2 Oe than the FeGaB thin film. The magnetic domain wall velocity for the FeGaB thin film is shown to be larger utilizing micromagnetic modeling due to its low anisotropy and the impact of spin–orbit coupling. As a result of our findings, it can be employed in microwave and spintronic applications.
