Anisotropy and temperature dependence of the spin-wave attenuation parameter in ferrite single crystals

Results are presented for ferromagnetic resonance in Mg-Mn and Li ferrites. The anisotropic part H_k of the spin-wave line width is defined as the difference between the spin-wave widths H_k as measured on a spherical specimen magnetized along [111] and [100] by parametric excitation of the spin waves by a longitudinal UHF magnetic field. The results are compared with the theory.Read at the All-Union Conference on Ferrites, Leningrad, 25 October 1963.
