“…[14]). Internal magnetic field in the magnetically ordered state of RFe 3 (BO 3 ) 4 splits also nonKramers doublets and shifts isolated energy levels, either due to magnetic interaction with neighboring levels or due to local magnetostriction.…”

“…The largest difference is observed for Y, B, and E bands. Table 3 lists the sums of strengths of seven f-f transitions in ErFe 3 (BO 3 ) 4 and ErAl 3 (BO 3 ) 4 and the lattice parameters affecting the f-f transition intensity: the Er-O distance and the angle between the bases of the triangular prism of oxygen ions, mea sured from the centrosymmetric prism state. The larg est value of this angle is 60°, i.e., the non centrosym metricity is close to maximum.…”

“…However, electric polariza D 3 7 tion in the ErFe 3 (BO 3 ) 4 crystal is very small [2]. At the same time, the ErAl 3 (BO 3 ) 4 crystal shows rather strong electric polarization in a magnetic field [3].…”

“…All RE fer roborates are magnetically ordered at temperatures below 30-40 K. In particular, ErFe 3 (BO 3 ) 4 becomes an easy plane antiferromagnet at temperature T N = 38 K [4][5][6] (iron magnetic moments are in the plane perpendicular to the C 3 axis of the crystal). Magnetic properties of RE ferroborates have a significant effect on their optical properties, in particular, on the f-f transition spectra (see, e.g., [7][8][9]); the f-f transitions in the Er 3+ impurity are widely used to study magnetic properties of different RE ferroborates (see, e.g., [4,10]). However, to our knowledge, optical properties of the stoichiometric ErFe 3 (BO 3 ) 4 crystal have not yet been studied.…”

Single crystals of the ErFe 3 (BO 3 ) 4 borate were synthesized and their structure was studied. Absorption spectra of the Er 3+ ion in σ and π polarizations of f-f transitions 4 I 15/2 4 I 13/2 , 4 I 11/2 , 4 I 9/2 , 4 F 9/2 , 4 S 3/2 , 2 H 11/2 , and 4 F 7/2 were measured. The refractive index and birefringence were measured as a func tion of the wavelength. The transition intensities were analyzed within the Judd-Ofelt theory, and the follow ing parameters of the theory were obtained: Ω 2 = 7.056 × 10 -20 cm 2 , Ω 4 = 1.886 × 10 -20 cm 2 , and Ω 6 = 2.238 × 10 -20 cm 2 . Using these parameters, the radiative transition probabilities, luminescence branching ratios, and radiative lifetimes of multiplets were calculated.

“…All RE ferroborates are magnetically ordered at temperatures below 30-40 K. In particular, Nd 0.5 Gd 0.5 Fe 3 (BO 3 ) 4 crystal becomes antiferromagnetic at T = 32 K [20]. The changes of magnetic and electric states of the RE ferroborates, both caused by the phase transitions or by the external fields, substantially influence the parameters of the f-f absorption spectra [21][22][23][24][25][26]. Such possibility exists also due to the optical magneto-electric effects [27][28][29][30].…”
