Аннотация: The magnetic resonance and field dependence of magnetization were studied in a single crystal of TbFe3(BO3)(4) at temperatures from 2 to 13K and frequencies from 18 to 142 GHz. Two pairs of lines with different intensities were found in the EPR spectrum. The found lines can be assigned to two types of centers: the Tb3+ ions which neighbor with the Bi and Mo growth impurities. The initial splitting of the lowest quasi-doublet of such Tb3+ ions by the crystal field and exchange field acting on the rare-earth ions from the iron sublattices were determined. The amount of these centers was estimated. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4792134]
