Critical fluctuations in the spin-orbit Mott insulator SrIrO
J. G. Vale, S. Boseggia, H. C. Walker +5
X-ray magnetic critical scattering measurements and specific heat measurements were performed on the perovskite iridate SrIrO. We find that the magnetic interactions cl…
Spin resonance in the superconducting state of LiFeODFeSe observed by neutron spectroscopy
N. R. Davies, M. C. Rahn, H. C. Walker +4
We have performed inelastic neutron scattering measurements on a powder sample of the superconductor lithium iron selenide hydroxide LiFeODFeSe ($x \simeq 0.1…
The importance of XY anisotropy in Sr2IrO4 revealed by magnetic critical scattering experiments
J. G. Vale, S. Boseggia, H. C. Walker +9
The magnetic critical scattering in SrIrO has been characterized using X-ray resonant magnetic scattering (XRMS) both below and above the 3D antiferromagnetic ordering temp…
Crystal field states of Tb3+ in the pyrochlore spin liquid Tb2Ti2O7 from neutron spectroscopy
A. J. Princep, H. C. Walker, D. T. Adroja +2
We report time-of-flight neutron scattering measurements of the magnetic spectrum of Tb3+ in Tb2Ti2O7. The data, which extend up to 120 meV and have calibrated intensity, enable us…
Circularly Polarised X-ray Scattering Investigation of Spin-Lattice Coupling in TbMnO in Crossed Electric and Magnetic Fields
H. C. Walker, F. Fabrizi, L. Paolasini +4
We present a study of the magnetic and crystallographic structure of TbMnO in the presence of crossed electric and magnetic fields using circularly polarised X-ray non-resonant…
Slaving of the magnetic moment canting to the correlated oxygen rotation in Sr2IrO4 revealed by X-ray resonant scattering
S. Boseggia, H. C. Walker, J. Vale +6
Sr2IrO4 is a prototype of the class of Mott insulators in the strong spin-orbit interaction (SOI) limit described by a ground state. In Sr2IrO4, the strong S…
The Magnetic Structure of DyMn2O5 Determined by Resonant X-ray Scattering
G. E. Johnstone, R. A. Ewings, R. D. Johnson +3
Resonant magnetic x-ray scattering has been used to investigate the magnetic structure of the magnetoelectric multiferroic DyMn2O5. We have studied the magnetic structure in the fe…
Antiferromagnetic order and domains in Sr3Ir2O7 probed by x-ray resonant scattering

This article reports a detailed x-ray resonant scattering study of the bilayer iridate compound, Sr3Ir2O7, at the Ir L2 and L3 edges. Resonant scattering at the Ir L3 edge has been…
Nature of the magnetic order and origin of induced ferroelectricity in TbMnO
S. B. Wilkins, T. R. Forrest, T. A. W. Beale +9
The magnetic structures which endow TbMnO with its multiferroic properties have been reassessed on the basis of a comprehensive soft x-ray resonant scattering (XRS) study. The…
Circularly polarised X-rays as a probe of non-collinear magnetic order in multiferroic TbMnO3
F. Fabrizi, H. C. Walker, L. Paolasini +4
Non-resonant X-ray magnetic scattering has been used to study the magnetic structure of multiferroic TbMnO3 in its ferroelectric phase. Circularly polarized X-rays were combined wi…
