        Summary
        In this thesis we set out to find signatures of magnonic black hole horizons in transport experiments. Using the stochastic Landau-Lifshitz-Gilbert equation, we perform calculation of the magnon-drag Peltier coefficient in the axial configuration that agrees with the result from B. Flebus et al. [11]. We generalize the calculation to the easy-plane configuration. Finally, we discovered a threshold value for the magnon drift velocity, which corresponds to the transition between a super- and subsonic regime for the magnons and show that the supersonic regime can be unstable.
