Zusammenfassung
Magnetic relaxation processes were investigated by ferromagnetic resonance (FMR) using crystalline Cr/Fe/GaAs(001) ultrathin film structures grown by molecular beam epitaxy (MBE). For Fe films thicker than 1.5 nm the extrinsic relaxation term showed evidence of two magnon scattering. Above 10 GHz the in-plane FMR linewidth was linearly dependent on the microwave frequency with ...
Magnetic relaxation processes were investigated by ferromagnetic resonance (FMR) using crystalline Cr/Fe/GaAs(001) ultrathin film
structures grown by molecular beam epitaxy (MBE). For Fe films thicker
than 1.5 nm the extrinsic relaxation term showed evidence of two magnon
scattering. Above 10 GHz the in-plane FMR linewidth was linearly
dependent on the microwave frequency with an appreciable zero-frequency
offset. The zero frequency offset measures the strength of extrinsic
damping. The in-plane Gilbert damping includes both the intrinsic and
extrinsic Gilbert contributions in qualitative agreement with recent
predictions by Arias and Mills.
