Magnetic order and dynamics of the charge-ordered antiferromagnet La1.5Sr0.5CoO4
L. M. Helme, A. T. Boothroyd, R. Coldea +7
We describe neutron scattering experiments performed to investigate the magnetic order and dynamics of half-doped La1.5Sr0.5CoO4. This layered perovskite exhibits a near-ideal chec…
Interplay between localized and itinerant d electrons in a frustrated metallic antiferromagnet, 2H-AgNiO2
A. I. Coldea, A. Carrington, R. Coldea +11
We report the electronic and magnetic behaviour of the frustrated triangular metallic antiferromagnet 2H-AgNiO2 in high magnetic fields (54 T) using thermodynamic and transport mea…
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…
