Emergence of a Novel Frozen Magnetic State in a Heavily Overdoped Non-Superconducting Copper Oxide (2009)

Sonier, J. E., Kaiser, C. V., Pacradouni, V., Sabok-Sayr, S. A., Cochrane, C., MacLaughlin, D. E., ...

The doping of charge carriers into the CuO2 planes of copper oxide Mott insulators causes a gradual destruction of antiferromagnetism and the emergence of high-temperature superconductivity. Optimal...

Detection of the Unusual Magnetic Orders in the Pseudogap Region of a High-Temperature Superconducting YBa2Cu3O6.6 Crystal by Muon-Spin Relaxation (2009)

Sonier, J. E., Pacradouni, V., Sabok-Sayr, S. A., Hardy, W. N., Bonn, D. A., Liang, R., ...

We present muon spin relaxation measurements on a large YBa2Cu3O6.6 single crystal in which two kinds of unusual magnetic order have been detected in the pseudogap region by neutron scattering. A...

Inhomogeneous Magnetic-Field Response of YBa2Cu3Oy and La2-xSrxCuO4 Persisting above the Bulk Superconducting Transition Temperature (2008)

Sonier, J. E., Ilton, M., Pacradouni, V., Kaiser, C. V., Sabok-Sayr, S. A., Ando, Y., ...

We report that in YBa2Cu3Oy and La2-xSrxCuO4 there is a spatially inhomogeneous response to magnetic field for temperatures T extending well above the bulk superconducting transition temperature Tc....

Spin-glass state of vortices in YBa2Cu3Oy and La2-xSrxCuO4 below the metal-to-insulator crossover (2007)

Highly disordered magnetism confined to individual weakly interacting vortices is detected by muon spin rotation in two different families of high-transition-temperature superconductors, but only in...

Hole doping dependences of the magnetic penetration depth and vortex core size in YBa2Cu3Oy: Evidence for stripe correlations near 1/8 hole doping (2007)

Sonier, J. E., Sabok-Sayr, S. A., Callaghan, F. D., Kaiser, C. V., Pacradouni, V., Brewer, J. H., ...

We report on muon spin rotation measurements of the internal magnetic field distribution n(B) in the vortex solid phase of YBa2Cu3Oy (YBCO) single crystals, from which we have simultaneously...
