Abstract

Optical absorption spectra of trigonal crystal TbFe 3 (BO 3 ) 4 have been studied in the region of 7 F 6 → 5 D 4 transition in Tb 3+ ion depending on temperature (2–220 K) and on magnetic field (0–60 kOe). Splitting of the Tb 3+ excited states, both under the influence of the external magnetic field and effective exchange field of the Fe-sublattice, have been determined. Landé factors of the excited states have been found. Stepwise splitting of one of the absorption lines has been discovered in the region of the Fe-sublattice magnetic ordering temperature. This is shown to be due to the abrupt change of equilibrium geometry of the local Tb 3+ ion environment only in the excited state of the Tb 3+ ion. In general, the magnetic ordering is accompanied by temperature variations of the Tb 3+ local environment in the excited states. The crystal field splitting components have been identified. In particular, it has been shown that the ground state (in D 3 symmetry approximation) consists of two close singlet states of A 1 and A 2 type, which are split and magnetized by effective exchange field of the Fe-sublattice. Orientations of magnetic moments of the excited electronic states relative to that of the ground state have been experimentally determined in the magnetically ordered state of the crystal. A pronounced shift of one of absorption lines has been observed in the vicinity of the TbFe 3 (BO 3 ) 4 structural phase transition. The temperature interval of coexistence of the phases is about 3 K. Copyright EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg 2011
