Abstract
NMR spectra on Fe-57 nuclei in yttrium iron garnet (YIG) containing Y3+ (a) defects and Al3+(d) substitutions were measured in the temperature range 4 .2-360 K in zero external magnetic field. The temperature dependencies of s atellite lines caused by Y3+ (a), Al3+ (d) impurities were determined. Theo retical description of the temperature behavior of the main and satellite l ines has been carried out in the frame of model based on the Bethe-Peierls- Weiss approximation.
