Abstract: A comparative analysis of magnetic properties of gadolinium ferroborates GdFe$_3$(BO$_3$)$_4$ grown from three different solvents: lithium tungstate [GdFe$_3$(BO$_3$)$_4$], trimolybdate-bismuth [GdFe$_3$(BO$_3$)$_4$ : Bi] and potassium-molybdate [GdFe$_3$(BO$_3$)$_4$ : Mo] melt solutions has been carried out. Phase diagrams of the magnetic state “temperature – magnetic field” of the investigated crystals have been constructed. It is shown that GdFe$_3$(BO$_3$)$_4$ does not contain uncontrolled impurities, whereas for GdFe$_3$(BO$_3$)$_4$ : Bi the incorporation of uncontrolled Bi$^{3+}$ impurities in small amounts ($\sim$ 6 at.%) is confirmed. For GdFe$_3$(BO$_3$)$_4$ : Mo, it was assumed that both Mo ions (of valence higher than 3+) and potassium ions K$^+$ are present as uncontrolled impurities.

Keywords: antiferromagnetics, multiferroics, spin reorientation transition.
