Suppression of the structural phase transition and lattice softening in slightly underdoped Ba(1-x)K(x)Fe2As2 with electronic phase separation (2009)

Inosov, D. S., Leineweber, A., Yang, Xiaoping, Park, J. T., Christensen, N. B., Dinnebier, R., ...

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 magnetic transition...

Direct Observation of Magnon Fractionalization in the Quantum Spin Ladder (2008)

Thielemann, B., Rüegg, Ch., Rønnow, H. M., Läuchli, A. M., Normand, B., ...

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 modes at low fields...

Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4 (2008)

Thielemann, B., Rüegg, Ch., Kiefer, K., Rønnow, H. M., Normand, B., Bouillot, P., ...

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 consequence of weak...

Tuning competing orders in La2-xSrxCuO4 cuprate superconductors by the application of an external magnetic field (2008)

Chang, J., Niedermayer, Ch., Gilardi, R., Christensen, N. B., Ronnow, H. M., McMorrow, D. F., ...

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 drives the system...
