Abstract
Raman spectra in the antiferromagnetic insulator phases of S = 1/2 high Tc superconducting cuprates were compared with S = 1 La2NiO4. The anomalous magnon spectra in cuprates suggests that the four-spin cyclic exchange interactions are very large. The doped carriers in cuprates show non-Fermi liquid behavior.
