Abstract
Absorption and magnetic circular dichroism (MCD) spectra of f-f transitions 6H15/2 → 6F3/2, 6F5/2, 6(F7/2 + H5/2) have been measured in cubic crystal Rb2NaDyF6 with Dy3+ ions in centrosymmetrical Oh positions. Magneto-optical activities (MOA) of the transitions (the ratio of zero moments of the MCD and absorption bands) have been obtained from the corresponding spectra. Origins of the transitions MOA have been analyzed and theoretical estimations of the MOA values have been made. It turned out, that MOA of the transitions in the centrosymmetrical crystal Rb2NaDyF6 (being allowed by odd vibrations) are noticeably larger than those in non-centrosymmetrical compounds, where f-f transitions are allowed by static odd components of crystal field.
