Abstract:The Faraday rotation (FR), magnetic circular dichroism (MCD), magnetic linear dichroism (MLD) and nuclear magnetic resonance (NMR) have been studied in the transparent ferrimagnet RbNiF3 (TC = 139°K). It was found that MCD and asymmetric anomalous dispersion of FR may be explained by the exchange splitting of electronic states of Ni2+ ions below TC. The structure and the temperature dependence of MCD of A23→1Ea transition confirms the model of magnetic structure with two unequivalent antiferromagnetically alig… Show more
