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...

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)

Sonier, J. E., Callaghan, F. D., Ando, Y., Kiefl, R. F., Brewer, J. H., Kaiser, C. V., ...

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)

Spin-glass magnetism confined to individual weakly interacting vortices is detected in two different families of high-transition-temperature (T_c) superconductors, but only in samples on the...

Muon spin rotation measurements of the vortex state in vanadium: A comparative analysis using iterative and analytical solutions of the Ginzburg-Landau equations (2006)

Laulajainen, M., Callaghan, F. D., Kaiser, C. V., Sonier, J. E.

We report muon spin rotation measurements on a single crystal of the marginal type-II superconductor V. The measured internal magnetic field distributions are modeled assuming solutions of the...

Field dependence of the vortex core size in a multi-band superconductor (2005)

Callaghan, F. D., Laulajainen, M., Kaiser, C. V., Sonier, J. E.

The magnetic field dependence of the vortex core size in the multi-band superconductor NbSe2 has been determined from muon spin rotation measurements. The spatially extended nature of the...
