Response of acoustic phonons to charge and orbital order in the 50\% doped bilayer manganite LaSrMnO
F. Weber, S. Rosenkranz, J. -P. Castellan +7
We report an inelastic neutron scattering study of acoustic phonons in the charge and orbitally ordered bilayer manganite LaSrMnO. For excitation energies less than $15…
Probing the connections between superconductivity, stripe order, and structure in La1.905Ba0.095Cu1-yZnyO4
Jinsheng Wen, Zhijun Xu, Guangyong Xu +11
The superconducting system La2-xBaxCuO4 is known to show a minimum in the transition temperature, Tc, at x = 1/8 where maximal stripe order is pinned by the anisotropy within the C…
From antiferromagnetic insulator to correlated metal in pressurized and doped LaMnPO
J. W. Simonson, Z. P. Yin, M. Pezzoli +17
Widespread adoption of superconducting technologies requires the discovery of new materials with enhanced properties, especially higher superconducting transition temperatures T$_{…
Anisotropic critical magnetic fluctuations in the ferromagnetic superconductor UCoGe
C. Stock, D. A. Sokolov, P. Bourges +6
We report neutron scattering measurements of critical magnetic excitations in the weakly ferromagnetic superconductor UCoGe. The strong non-Landau damping of the excitations we obs…
Common origin of the two types of magnetic fluctuations in iron chalcogenides
Songxue Chi, J. A. Rodriguez-Rivera, J. W. Lynn +5
We use inelastic neutron scattering to study the low energy spin excitations in moderately doped non-superconducting FeTeSe. The spin excitations in this…
Quantum spin liquid in frustrated one dimensional LiCuSbO4
S. E. Dutton, M. Kumar, M. Mourigal +8
A quantum magnet, LiCuSbO4, with chains of edge-sharing S = 1/2 CuO6 octahedra is reported. While the Curie-Weiss constant is ferromagnetic, θ= 30 K, no phase transition or spin fr…
