Abstract

The spin excitations and the lattice vibrations in the insulator phase of the electronic superconductor Pr₂CuO₄ were investigated by wide-range Raman spectroscopy. The origin of the anomalous magnon spectra as in the case of the hole superconducting cuprates are assigned to the four-spin cyclic exchange interactions. The obtained two-spin superexchange integral J is 1040 cm^-1. The phonon energies are 233 cm^-1 in A_lg, 287 cm^-1 in B_lg, and 165 and 474 cm^-1 in E_g.
