| Abstract: | An attempt has been made to review the ferromagnetic resonance and relaxation data on rare earth iron garnets and in the light
of it, to analyze the data on Sm and Eu thin films and Gd and Dy bulk polycrystalline samples obtained in our laboratory.
A phenomenological approach adopted to explain the temperature and composition dependence of the line width andg
eff appears to explain the complex spectra in most cases. |
