摘要：

The difference between the magnetic properties in the overdoped and the underdoped regime, that is mainly the opening of a spin gap well above T-c in underdoped samples, is discussed on the basis of NMR data obtained in YBCO single crystals. We also make a quantitative comparison between NMR and inelastic neutron scattering obtained on the same single crystals.
