Abstract: Crystal-field transitions within the 3H4 multiplet of Pr3+ in Pr2CuO4 were studied by Raman scattering as a function of temperature. We observed three crystal-field excitations at 156, 540, and 675 cm-1. The peak at 156 cm-1, assigned by other authors to the lowest Eg phonon mode, shows a thermal broadening of the linewidth, which is the signature for acoustical-phonon-relaxation processes between crystal-field levels. Our results are in excellent agreement with recent inelastic neutron scattering experiments in Pr2CuO4. © 1994 The American Physical Society.
