Charge ordering in Ortho-VIII YBCO

DOI

The relationship between spin and charge correlations (stripes) continues to be one of the major issues in high temperature (cuprate) superconductivity. Under some circumstances the charges in the CuO2 plane of the layered cuprates can order in zero magnetic field to form stripes, that is a modulation in charge density accompanied by a lattice distortion. An exciting experimental developments in this area is the observation of a temperature and field dependent splitting of the high-field Cu2F lines in the NMR spectrum. This has been interpreted as evidence for charge order in ortho-II and ortho-VIII YBa2Cu3Oy. In a recent test experiment on D11 at ILL we saw evidence for a Bragg peak on the edge of the detector which is consistent with charge order in ortho-VIII YBa2Cu3Oy. This experiment verify whether this peak is real and search for other peaks.
