摘要：

We have performed a Raman scattering study for single crystals of the rare-earth ( RE) iron borates RFe3(BO3)(4), R = Nd, Tb, Pr, in the range of temperatures 3-300.. Electronic Raman scattering on the 4f levels of RE ions was registered, which enabled us to specify the schemes of crystal-field levels within ground multiplets of the RE ions. A splitting of the Kramers doublets in electronic Raman spectra of the neodymium iron borate testifies a magnetic ordering of the compound. Raman scattering from a coupled mode of the spin oscillations of the Fe and Nd subsystems was observed in NdFe3( BO3)(4).
