Glassy low-energy spin fluctuations and anisotropy gap in La1.88Sr0.12CuO4
A. T. Rømer, J. Chang, N. B. Christensen +13
We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (Tc=27 K). The temperature dependence of the low-energy in…
Spin density wave induced disordering of the vortex lattice in superconducting LaSrCuO
J. Chang, J. S. White, M. Laver +19
We use small angle neutron scattering to study the superconducting vortex lattice in LaSrCuO as a function of doping and magnetic field. We show that near optimally…
Tuning competing orders in La2-xSrxCuO4 cuprate superconductors by the application of an external magnetic field
J. Chang, Ch. Niedermayer, R. Gilardi +13
We report the results of a combined muon spin rotation and neutron scattering study on La2-xSrxCuO4 in the vicinity of the so-called 1/8-anomaly. Application of a magnetic field dr…
Magnetic-field-induced spin excitations and renormalized spin gap of the underdoped superconductor LaSrCuO
J. Chang, A. P. Schnyder, R. Gilardi +15
High-resolution neutron inelastic scattering experiments in applied magnetic fields have been performed on LaSrCuO (LSCO). In zero field, the temperature…
Direct observation of the flux-line vortex glass phase in a type II superconductor
U. Divakar, A. J. Drew, S. L. Lee +10
The order of the vortex state in La_{1.9} Sr_{0.1} CuO_{4} is probed using muon spin rotation and small-angle neutron scattering. A transition from a Bragg glass to a vortex glass…
Muons as Local Probes of Three-body Correlations in the Mixed State of Type-II Superconductors
G. I. Menon, A. Drew, U. K. Divakar +10
The vortex glass state formed by magnetic flux lines in a type-II superconductor is shown to possess non-trivial three-body correlations. While such correlations are usually diffic…
