Origin of magnetic excitation gap in double perovskite SrFeOsO
A. E. Taylor, R. Morrow, M. D. Lumsden +8
SrFeOsO is an insulating double perovskite compound which undergoes antiferromagnetic transitions at 140 K () and 67 K (). To study the underlying electroni…
Strong anisotropy within a Heisenberg model in the J=1/2 insulating state of Sr2Ir0.8Ru0.2O4
S. Calder, J. W. Kim, A. E. Taylor +5
The dispersive magnetic excitations in Sr2IrO4 have previously been well described within an isospin-1/2 Heisenberg model on a square lattice that revealed parallels with La2CuO4.…
Spin-orbit coupling controlled electronic ground state in 5 oxides
A. E. Taylor, S. Calder, R. Morrow +6
Entanglement of spin and orbital degrees of freedom drives the formation of novel quantum and topological physical states. Discovering new spin-orbit entangled ground states and em…
Strongly Gapped Spin-Wave Excitation in the Insulating Phase of NaOsO3
S. Calder, J. G. Vale, N. Bogdanov +13
NaOsO3 hosts a rare manifestation of a metal-insulator transition driven by magnetic correlations, placing the magnetic exchange interactions in a central role. We use resonant ine…
X-ray scattering study of pyrochlore iridates: crystal structure, electronic and magnetic excitations
J. P. Clancy, H. Gretarsson, E. K. H. Lee +12
We have investigated the structural, electronic, and magnetic properties of the pyrochlore iridates Eu2Ir2O7 and Pr2Ir2O7 using a combination of resonant elastic x-ray scattering,…
Magnetic excitation spectrum of Na2IrO3 probed with resonant inelastic x-ray scattering
H. Gretarsson, J. P. Clancy, Yogesh Singh +8
The low energy excitations in Na2IrO3 have been investigated using resonant inelastic x-ray scattering (RIXS). A magnetic excitation branch can be resolved, whose dispersion reache…
