Abstract
Raman, photoluminescence and infrared studies of Nd2O3-A polytype pell ets are undertaken in order to study further the phonon-crystal field coupling of the Nd3+ ion that has been observed in NdBa2Cu3O7-x and Nd 2CuO4+delta. We conclude that symmetry considerations and closeness in frequency do not guarantee the existence of an interaction. On the ot her hand the 3-4 cm(-1) splittings of Kramers doublets observed in Nd2 CuO4+delta is detected in Nd2O3 for magnetic fields of few Tesla corro borating thus the predicted local magnetic field magnitude due to the Cu polarization field on the Nd3+ sites.
