The understanding of the damping processes of the magnetization dynamics is an important issue. Several different damping channels are proposed. Here the importance of magnon-magnon processes for the damping is investigated with a magneto-optical method. This method allows to determine the length of the magnetization vector and therefore gives an indication for magnon-magnon processes. Higher order magneto-optic effects are also taken into account, which allows the determination of the quadratic magneto-optic constant.
