We present the results of the magnetic and heat capacity study of a magnetic phase diagram of a HoFe(3)(BO(3))(4) single crystal. Two magnetic phase transitions are found in the low-temperature region. The transition from the paramagnetic to easy-plane antiferromagnetic state occurs at T(N) = 37.4 K and is independent of an applied magnetic field. The sharp(More)
Neutron diffraction, susceptibility and magnetization measurements (for R = Er only) were performed on iron borates RFe(3)(BO(3))(4) (R = Pr, Er) to investigate details of the crystallographic structure, the low temperature magnetic structures and transitions and to study the role of the rare earth anisotropy. PrFe(3)(BO(3))(4), which crystallizes in the(More)
The Faraday effect induced by an external magnetic field in TbFe₃(BO₃)₄ and TbAl₃(BO₃)₄ borates at a wavelength 633 nm has been investigated. It was found that the terbium subsystem brings the dominant magnetic contribution to the Faraday rotation at low temperatures in borate TbFe₃(BO₃)₄. For both TbFe₃(BO₃)₄ and TbAl₃(BO₃)₄ the magneto-optical(More)
The magnetic structure of the mixed rare-earth system Pr x Y1-x Fe3(BO3)4 (x  =  0.75, 0.67, 0.55, 0.45, 0.25) was studied via magnetic and resonance measurements. These data evidence the successive spin reorientation from the easy-axis antiferromagnetic structure formed in PrFe3(BO3)4 to the easy-plane one of YFe3(BO3)4 associated with the weakening of the(More)
The linear birefringence induced by the electric field was first detected in a TmAl<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub> single crystal. The electric field dependence of the birefringence was investigated. The estimation of the electro-optical coefficient of the material gives ≈1.5×10<sup>-10</sup>  cm/V for a wavelength 632.8 nm.
The present paper reports on the specific heat and magnetization of the YFe(3)(BO(3))(4) and ErFe(3)(BO(3))(4) single crystals. In both compounds, antiferromagnetic order of the iron spins evolves at T(N) = 38 K. The experimental data suggest that the magnetic moments are in the basal plane of the trigonal crystal for both compounds. In the magnetically(More)
