Abstract :
The Raman spectra of CaFe2O4 were measured with several exact scattering configurations between 20 and 520 K and the symmetry of all observed Raman lines was determined. The Ag and B2g lines were assigned to definite phonon modes by comparison to the results of lattice dynamical calculations. No anomaly of phonon parameters was observed near the magnetic ordering temperature TN=160 K.
