Destabilization of magnetic order in a dilute Kitaev spin liquid candidate
P. Lampen-Kelley, A. Banerjee, A. A. Aczel +6
The insulating honeycomb magnet -RuCl exhibits fractionalized excitiations that signal its proximity to a Kitaev quantum spin liquid (QSL) state, however, at , fragil…
Hidden Order Signatures in the Antiferromagnetic Phase of U(RuFe)Si
T. J. Williams, M. N. Wilson, A. A. Aczel +2
We present a comprehensive set of elastic and inelastic neutron scattering measurements on a range of Fe-doped samples of U(RuFe)Si with 0.01~~0.15.…
Spin-orbit coupling control of anisotropy, ground state and frustration in 5d2 Sr2MgOsO6
Ryan Morrow, Alice E. Taylor, D. J. Singh +10
The influence of spin-orbit coupling (SOC) on the physical properties of the 5d2 system Sr2MgOsO6 is probed via a combination of magnetometry, specific heat measurements, elastic a…
Weak coupling of pseudoacoustic phonons and magnon dynamics in incommensurate spin ladder compound Sr14Cu24O41
Xi Chen, Dipanshu Bansal, Sean Sullivan +5
Intriguing lattice dynamics has been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon…
Highly-anisotropic exchange interactions of iridium moments on the fcc lattice in LaIrO ( Mg, Zn)
A. A. Aczel, A. M. Cook, T. J. Williams +6
We have performed inelastic neutron scattering (INS) experiments to investigate the magnetic excitations in the weakly distorted face-centered-cubic (fcc) iridate double perovskite…
Fragile singlet ground state magnetism in pyrochlore osmates R2Os2O7 (R=Y and Ho)
Z. Y. Zhao, S. Calder, A. A. Aczel +7
The singlet ground state magnetism in pyrochlore osmates YOsO and HoOsO is studied by DC and AC susceptibility, specific heat, and neutron powder diffractio…
