Sm_1−xLa_xFe₃(BO₃)₄ (x = 0, 0.75) single crystals were synthesized using the flux method. The crystal nucleation procedure and flux parameters are described. The prepared single crystals were studied by Raman spectroscopy. Raman spectra anomalies related to the magnetic ordering established in both compounds were found. The main changes occur in the low-wavenumber region (up to 100 cm⁻¹), where the modes corresponding to magnon scattering arise.
