| Abstract: | The wavevector and temperature dependence of the spinwave linewidth in yttrium iron garnets has been studied for polycrystalline samples of average grain diameter 12·8µm and has been compared with the calculated relaxation times of basic three-magnon confluence and four-magnon scattering processes. |
