“…The samarium ferroborate SmFe 3 (BO 3 ) 4 single crystal was grown from a Bi 2 Mo 3 O 12 based solutionmelt [6]. We will use the orthogonal system of coordi nates (x, y, z), where x and z coincide with the crystal lographic directions a and c, respectively, and direc tion y is perpendicular to an xz plane.…”

A change in the magnetization of a SmFe 3 (BO 3 ) 4 single crystal in response to an applied alternat ing electric field has been experimentally observed for the first time. The measurements have demonstrated that the magnetization oscillates not only at a frequency of the applied electric field but also at twice the fre quency. The dependences of the magnetoelectric effect on the magnetic and electric fields and temperature have been measured. It has been assumed that the existence of the second harmonic of the magnetoelectric effect is due to the electrostriction.

“…1). While in the case of Pr, Nd, and Sm iron borates the structure is described by the R32 ( 3 7 ) space group at all temperatures [2,3] [2][3][4][5], RFe3(BO3)4 with smaller R 3+ ions undergo a structural phase transition into an also trigonal but less symmetric P3121( 3 4 ) phase [6,2] at temperatures that linearly grow with diminishing the ionic radius of R 3+ [7].…”

We present a comparative far-infrared reflection spectroscopy study of phonons, phase transitions, spin-phonon and electron-phonon interactions in isostructural multiferroic iron borates of gadolinium and terbium. The behavior of phonon modes registered in a wide temperature range is consistent with a weak first-order structural phase transition (Ts = 143 for GdFe3(BO3)4 and 200 K for TbFe3(BO3)4) from high-symmetry high-temperature R32 structure into low-symmetry low-temperature P3121 one. The temperature dependences of frequencies, oscillator strengths, and damping constants of some low-frequency modes reveal an appreciable lattice anharmonicity. Peculiarities in the phonon mode behavior in both compounds at the temperature of an antiferromagnetic ordering (TN = 32 K for GdFe3(BO3)4 and 40 K for TbFe3(BO3)4) evidence the spin-phonon interaction. In the energy range of phonons, GdFe3(BO3)4 has no electronic levels but TbFe3(BO3)4 possesses several ones. We observe an onset of new bands in the excitation spectrum of TbFe3(BO3)4, due to a resonance interaction between a lattice phonon and 4f electronic crystal-field excitations of Tb 3+ . This interaction causes delocalization of the CF excitations, their Davydov splitting, and formation of coupled electron-phonon modes.

“…As it is seen, there is a splitting of absorption lines in both spectral ranges below the temperature about T N = 32 K, which corresponds to the temperature of magnetic phase transition. This splitting is caused by the double Kramers degeneracy removal of the energy levels by exchange interactions of the samarium and iron ions, which magnetic moments orient in planes ┴ c …”

The paper demonstrates possibilities of observation and thermal dependency study of the absorption lines as a co-product of Raman spectroscopy study in SmFe 3 (BO 3 ) 4 ferroborate. Raman spectra of the ferroborate were studied in a wide temperature range (T = 10÷300 K). Temperature-dependent absorption lines sensitive to the magnetic phase transition have been observed in Raman spectra at two spectral ranges.
