Abstract [en]
Magnetic isotropic and Dzyaloshinskii-Moriya interactions in yttrium iron garnet have been obtained byab initio fully relativistic calculations. The calculated coupling constants are in agreement with availableexperimental data. Using linear spin-wave theory, we are able to reproduce the experimental magnon spectrumincluding the spin-wave gap and stiffness. The way to calculate the exchange coupling constants using theKorringa-Kohn-Rostoker formalism for large magnetic systems such as complex oxides is discussed in detail.
