摘要：

The study of Mössbauer spectra of the solid solution 0.905 Cr2O3—0.035 Fe2O3 at different temperatures in the range 10 to 293 °K has revealed spin relaxation effects in this antiferromagnetically ordered system in a wide temperature range (100 to 289 °K) below the Néel temperature (289 °K). The variation of the hyperfine field with temperature is found to be almost linear from 10 °K onward. Above 100 °K the hyperfine field calculated from the total splitting is more than that obtained from ground state splitting. The observed results are compared with the existing spin‐flip theory based on a stochastic model. Copyright © 1969 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
