This work presents the results of numerical calculations of magnetostatic surface waves (MSSWs) losses caused by spin pumping mechanism at propagation in a ferrite film covered by a metal with the strong spin-orbit interaction. The calculations were carried out within the framework of known model taking into account the influence of spin pumping on MSSW propagation through the imaginary part of the complex pinning parameter at the ferrite/metal interface. The cases of frequency-dependent and constant pinning parameters are considered and obtained results were compared with the experimental data. Keywords: spin waves, pinning parameter, propagation losses, yttrium-iron garnet.
