Characteristic features of the spin excitations in high-T~ cuprates revealed by neutron scattering and nuclear magnetic resonance experiments are summarised, and analysed on the basis of the slave-boson mean-field theory for the extended t-J model, placing special emphasis on the spin-gap phenomenon

The short wavelength behavior of spin excitations has been investigated by means of 2-magnon Raman spectroscopy in YBa2Cu306+ x , La2CuO4, and Nd2CuO 4. The resonance behavior indicates a scattering mechanism via a Cu-3d O-2p charge tran.qfer excitation. In the undoped material the temperature depen
