Abstract
We report on microwave photovoltage and simultaneous magnetotransport measurements in a Ga, Mn As film oriented normal to the magnetic field. We detect the ferromagnetic resonance over a broad frequency range of 2–18.5 GHz and determine the spectroscopic g-factor and separate the Gilbert from the inhomogeneous contribution to magnetization relaxation. Temperature dependent measurements below the ...
