| Abstract: | The magnetic hyperfine interactions of the impurity Sb5+ in Cr2O3 have been examined by the Mössbauer effect of 121Sb.The magnetic field on the nucleus of 121Sb5+ (Cr2O3) measured at 77° K, H(0) = 170 ± 15 koe.The comparison of the results obtained for the impurity 121Sb5+ with those for the 119Sn4+ ions, occuring in the same matrix, suggests the preponderant effect of the decoupling of the electron spins of 5s valency on the values of the internal fields observed for those ions. |
