We will present a setup in which we can determine the influence of non polarized and circular polarized light on the different damping mechanisms as a function of wavelength, polarization, helicity, intensity and angle between magnetization (M) and input direction of the polarized light.

Therefore we have a new setup in which it is possible to do multifrequency Ferromagnetic Resonance (FMR) and Magneto-Optical Kerr Effect (MOKE) measurements simultaneously. The FMR setup is used with a microwave short-circuit and has a frequency range of 1 up to 40 GHz. In addition the setup enables us to do measurements with and without field modulation. The MOKE setup can be used at longitudinal and transversal geometry and one can measure from infrared to visible light by using different types of lasers.

By combining this two setups we will determine the interaction of Ferromagnetic Resonance with light of different polarization, helicity and wavelength.
