In this thesis the effect of interfacial Dzyaloshinskii-Moriya-interaction (iDMI) is studied. This effect, which induces a frequency shift of spin waves with fixed wave vector, is investigated for different multilayers. Only spin waves with its wave vector perpendicular to the magnetization are detected. These spin waves are called surface waves. Brillouin light scattering (BLS) technique is used for the wave vector dependent detection of spin wave frequencies. Different setups were build and compared including a new setup, which does not use a focusing lens in front of the sample. This setup exhibits an increased wave vector resolution and simplifies changing between different samples. However, the signal intensity obtained by this setup is too low to measure spin waves under the given circumstances in reasonable time.
