Аннотация: The temperature dependence of the absorption spectra and magnetic circular dichroism due to f-f transitions from the H-6(15/2) to F-6 (5/2) and (6)(F (7/2) + H (5/2)) states in the Dy3+ ion in (Dy2O3-P2O5-SiO2-GeO2) and (Dy2O3-La2O3-Al2O3-B2O3-SiO2-GeO2) glasses and the temperature dependence of the Faraday effect were studied. TheПоказать полностьюtemperature dependence of the Faraday effect caused by f-d transitions was found to differ from that of the magnetic circular dichroism due to f-f transitions. It was shown that f-f transitions occur preferentially in Dy3+ ions associated into clusters. The origin of the paramagnetic magneto-optical activity of f-f transitions was analyzed. It was shown that the contributions to this activity can differ in value and sign and that the ratio between these contributions depends on the transition type. In some cases, this difference results in an anomalous temperature dependence of the magneto-optical activity.
