A. Snezhko et al., Temperature dependence of satellite structure of yttrium iron garnet containing Y3+ (a) defects and Al3+ (d) substitutions: experiment and model, J MAGN MAGN, 234(2), 2001, pp. 227-232
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. (C) 2001 Elsevier Science B.V. All rights reserved.
