Abstract

The optical studies of charge excitations and lattice in La_1.2(Sr_1.8-xCa_x)Mn₂O₇ were presented. It was found that the observed anomalies of the Raman phonon parameters were due to a strong spin-phonon coupling. The spin-phonon coupling was caused by the oxygen phonon modulation of the Mn-Mn spin exchange interaction.
