Abstract

Inelastic neutron scattering experiments have been carried out on YBa2Cu3O6+x single crystals in order to perform a systematic investigation of the spin dynamics in the various typical regimes : the pure and doped AF-states (x = 0.15, 0.37), the weakly doped metallic and superconducting state (x= 0.45, 0.51) and the heavily doped metallic state with the Tc= 60 K (x = 0.69) and Tc = 90 K (x = 0.92) phases. The major results are the strong effect of hole doping on the AF-order, the persistence of dynamical AF-correlations in the metallic state and the observation of an energy gap in the spin excitation spectrum at low temperatures in superconducting samples.
