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 $15…
From antiferromagnetic insulator to correlated metal in pressurized and doped LaMnPO
J. W. Simonson, Z. P. Yin, M. Pezzoli +17
Widespread adoption of superconducting technologies requires the discovery of new materials with enhanced properties, especially higher superconducting transition temperatures T$_{…
Magnetic field tuning of antiferromagnetic YbPt
L. S. Wu, Y. Janssen, C. Marques +8
We present measurements of the specific heat, magnetization, magnetocaloric effect and magnetic neutron diffraction carried out on single crystals of antiferromagnetic YbPt$_…
Evolution of the commensurate and incommensurate magnetic phases of the S = 3/2 kagome staircase Co3V2O8 in an applied field
Joel S. Helton, Ying Chen, Georgii L. Bychkov +4
Single crystal neutron diffraction studies have been performed on the S = 3/2 kagome staircase compound Co3V2O8 with a magnetic field applied along the magnetization easy-axis (H |…
Quantum spin fluctuations in the spin liquid state of Tb2Ti2O7
Hiroshi Takatsu, Hiroaki Kadowaki, Taku J. Sato +4
Neutron scattering experiments on a polycrystalline sample of the frustrated pyrochlore magnet Tb2Ti2O7, which does not show any magnetic order down to 50 mK, have revealed that it…
Antiferromagnetic spin excitations in single crystals of nonsuperconducting Li1-xFeAs
Meng Wang, X. C. Wang, D. L. Abernathy +9
We use neutron scattering to determine spin excitations in single crystals of nonsuperconducting Li1-xFeAs throughout the Brillouin zone. Although angle resolved photoemission expe…
