The Raman spectra of four crystals of TbFe 3– x Ga x (BO 3 ) 4 solid solutions ( x from 0 to 0.54) were studied in the temperature range from 8 to 350 K. The temperatures of structural phase transitions were determined. The observed spectral behavior is characteristic to condensation and restoration of soft modes. Soft modes are associated with a structural phase transition from the R 32 phase to the P 3 1 21 phase. The Compositions-Temperature phase diagram was constructed.
