Intra-Unit-Cell magnetism in optimally doped YBa2Cu3O7-delta
An intra-unit-cell (IUC) magnetism develops below the pseudo-gap (PG) temperature, T*, in the phase diagram of cuprate superconductors. Since the PG state is considered as being the mother-state out of which superconductivity emerges, it becomes crucial to understand the intrinsic nature of the IUC magnetic correlations and to search for the existence of related fluctuations that could contribute to generate anomalous electronic properties (marginal Fermi liquid, d-wave superconductivity). The present polarized neutron experiment is a continuation of our previous experiment on Thales (Exp. 4-02-541). It will be devoted to the study of the temperature evolution of the IUC magnetic signal, to confirm the observed drop down of the intensity below Tc. We will aslo search for new low energy magnetic fluctuations around the wave vector associated with the IUC magnetism reported by polarized neutron diffraction. The experiment will be performed on an optimally doped YBa2Cu3O6.9 single crystal free from the parasitic green phase. To this aim, we ask for 7 days on Thales equipped with cryopad.
