摘要：

Mossbauer spectroscopy at low temperature and in the presence of high magnetic field was used to investigate the cation distribution and spin canting angles in Cu0.5Zn0.5Fe2O4 samples substituted with the rare earth ions Sin and Nd. Observed variations in saturation magnetization and Curie temperature in the samples have been explained on the basis of site distributions and the strength of the exchange interactions between magnetic ions.
