Cascade of field-induced magnetic transitions in a frustrated antiferromagnetic metal
A. I. Coldea, L. Seabra, A. McCollam +10
Frustrated magnets can exhibit many novel forms of order when exposed to high magnetic fields, however, much less is known about materials where frustration occurs in the presence…
Direct observation of charge order in triangular metallic AgNiO2 by single-crystal resonant X-ray scattering
G. L. Pascut, R. Coldea, P. G. Radaelli +5
We report resonant X-ray scattering measurements on the orbitally-degenerate triangular metallic antiferromagnet 2H-AgNiO2 to probe the spontaneous transition to a triple-cell supe…
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…
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…
