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…
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…
