Abstract

Absorption and magnetic circular dichroism (MCD) spectra in the region of the ³H₆ → ³H₄, ³H₆ → ³F₃, ³F ₂, ³H₆ → ¹G₄, ³H₆ → ¹D₂ electron transitions and also luminescence spectrum of the ¹D₂ → ³F₄ transition in Tm³⁺ ion in the TmAl ₃(BO₃)₄ single crystal were measured in the temperature range 95-290 K. Temperature dependences of magneto-optical activity (MOA) of the absorption bands (ratio of the zero moments of MCD and absorption bands) were determined. Mechanisms responsible for MOA of f-f transitions and its temperature dependence in ions with the integer total magnetic moment are analyzed. It is shown that in TmAl₃(BO₃)₄ crystal the temperature-independent paramagnetic effect due to mixing of the electronic states by the magnetic field (so-called B-term) gives the prevailing contribution into MOA of the studied f-f transitions. In contrast to the absorption, luminescence spectrum demonstrates no MOA.
