Spin dynamics of frustrated easy-axis triangular antiferromagnet 2H-AgNiO2 explored by inelastic neutron scattering
E. M. Wheeler, R. Coldea, E. Wawrzynska +6
We report inelastic neutron scattering measurements of the spin dynamics in the layered hexagonal magnet 2H-AgNiO2 which has stacked triangular layers of antiferromagnetically-coup…
Charge disproportionation and collinear magnetic order in the frustrated triangular antiferromagnet AgNiO2
E. Wawrzynska, R. Coldea, E. M. Wheeler +5
We report a high-resolution neutron diffraction study of the crystal and magnetic structure of the orbitally-degenerate frustrated metallic magnet AgNiO2. At high temperatures the…
Anomalous temperature evolution of the internal magnetic field distribution in the charge-ordered triangular antiferromagnet AgNiO2
T. Lancaster, S. J. Blundell, P. J. Baker +6
Zero-field muon-spin relaxation measurements of the frustrated triangular quantum magnet AgNiO2 are consistent with a model of charge disproportionation that has been advanced to e…
Orbital degeneracy removed by charge order in triangular antiferromagnet AgNiO2
E. Wawrzynska, R. Coldea, E. M. Wheeler +6
We report a high-resolution neutron diffraction study on the orbitally-degenerate spin-1/2 hexagonal antiferromagnet AgNiO2. A structural transition to a tripled unit cell with exp…
