Field-induced soft-mode quantum phase transition in LaSrCuO
J. Chang, N. B. Christensen, Ch. Niedermayer +13
Inelastic neutron-scattering experiments on the high-temperature superconductor LaSrCuO reveal a magnetic excitation gap that decreases continuously u…
Magnetic-field-enhanced incommensurate magnetic order in the underdoped high-temperature superconductor YBa(2)Cu(3)O(6.45)
D. Haug, V. Hinkov, A. Suchaneck +10
We present a neutron-scattering study of the static and dynamic spin correlations in the underdoped high-temperature superconductor YBa(2)Cu(3)O(6.45) in magnetic fields up to 15 T…
Direct Observation of Magnon Fractionalization in the Quantum Spin Ladder
B. Thielemann, Ch. Rüegg, H. M. Rønnow +12
We measure by inelastic neutron scattering the spin excitation spectra as a function of applied magnetic field in the quantum spin-ladder material (C5H12N)2CuBr4. Discrete magnon m…
Fermi surface and order parameter driven vortex lattice structure transitions in twin-free YBa2Cu3O7
J. S. White, V. Hinkov, R. W. Heslop +12
We report on small-angle neutron scattering studies of the intrinsic vortex lattice (VL) structure in detwinned YBa2Cu3O7 at 2 K, and in fields up to 10.8 T. Because of the suppres…
Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4
B. Thielemann, Ch. Rüegg, K. Kiefer +18
Neutron diffraction is used to investigate the field-induced, antiferromagnetically ordered state in the two-leg spin-ladder material (Hpip)2CuBr4. This "classical" phase, a conseq…
Electronic structure near the 1/8-anomaly in La-based cuprates
J. Chang, Y. Sassa, S. Guerrero +13
We report an angle resolved photoemission study of the electronic structure of the pseudogap state in \NdLSCO ( K). Two opposite dispersing Fermi arcs are the main result of…
