Suppression of the structural phase transition and lattice softening in slightly underdoped Ba(1-x)K(x)Fe2As2 with electronic phase separation
D. S. Inosov, A. Leineweber, Xiaoping Yang +12
We present x-ray powder diffraction (XRPD) and neutron diffraction measurements on the slightly underdoped iron pnictide superconductor Ba(1-x)K(x)Fe2As2, Tc = 32K. Below the magne…
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…
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…
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…
Multiple Magnon Modes and Consequences for the Bose-Einstein Condensed Phase in BaCuSi2O6
Ch. Rüegg, D. F. McMorrow, B. Normand +7
The compound BaCuSi2O6 is a quantum magnet with antiferromagnetic dimers of S = 1/2 moments on a quasi-2D square lattice. We have investigated its spin dynamics by inelastic neutro…
Magnetic Proximity Effect in Perovskite Superconductor/Ferromagnet Multilayers
J. Stahn, J. Chakhalian, C. Niedermayer +8
superconducting/ferromagnetic (SC/FM) multilayers have been studied by neutron reflectometry. Evidence for a characteristic difference…
