Coherent spin waves in a maximal entropy phase
Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…
Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering
Arnau Romaguera, Elizabeth Skoropata, Yun Yen +18
Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations -- magnons -- mediate these flows i…
Large out-of-equilibrium magnetocaloric effect in rare-earth zirconate pyrochlores
O. Benton, Y. Skourski, D. Gorbunov +7
We explore the magnetic properties of NdZrO and PrZrO single crystals subjected to pulsed magnetic fields up to 60 T using magnetization and magnetocaloric-…
An inelastic neutron scattering study of the magnetic field dependence of the quantum dipolar garnet: YbGaO
Edward Riordan, Monica Ciomaga Hatnean, Geetha Balakrishnan +5
The garnet compound YbGaO is a fascinating material that is considered highly suitable for low-temperature refrigeration, via the magnetocaloric effect, in addition…
Magnetic properties of the zigzag ladder compound SrTb2O4
F. Orlandi, M. Ciomaga Hatnean, D. A. Mayoh +11
We report on the properties of SrTb2O4, a frustrated zigzag ladder antiferromagnet, studied by single crystal neutron diffraction (with polarised neutrons in zero field and unpolar…
Electrical transport signatures of metallic surface state formation in the strongly-correlated insulator FeSb2
Alexander G. Eaton, Nicholas J. M. Popiel, Ke-Jun Xu +8
We present local and nonlocal electrical transport measurements of the correlated insulator FeSb. By employing wiring configurations that delineate between bulk- and surface-do…
