Spindynamics in the antiferromagnetic phases of the Dirac metals MnBi ( Sr, Ca)
Marein C. Rahn, Andrew J. Princep, Andrea Piovano +4
The square Bi layers in MnBi ( Sr, Ca) host Dirac fermions which coexist with antiferromagnetic order on the Mn sublattice below K (Sr) and $270\,…
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…
Three-Dimensional Spin Fluctuations in Na0.75CoO2
L. M. Helme, A. T. Boothroyd, R. Coldea +4
We report polarized- and unpolarized-neutron scattering measurements of magnetic excitations in single-crystal Na0.75CoO2. The data confirm ferromagnetic correlations within the co…
Magnetic excitations in LaSrCoO
L. M. Helme, A. T. Boothroyd, D. Prabhakaran +3
We report magnetization and neutron scattering measurements of the half-doped compound LaSrCoO, which exhibits a checkerboard pattern of charge ordering below ~…
Spin correlations among the charge carriers in an ordered stripe phase
A. T. Boothroyd, P. G. Freeman, D. Prabhakaran +4
We have observed a diffuse component to the low-energy magnetic excitation spectrum of stripe-ordered La5/3Sr1/3NiO4 probed by neutron inelastic scattering. The diffuse scattering…
Magnetic Order and Dynamics in Stripe-Ordered La2-xSrxNiO4
A. T. Boothroyd, P. G. Freeman, D. Prabhakaran +2
We have studied magnetic correlations in several compositions of stripe-ordered La2-xSrxNiO4. In this paper we show how polarized-neutron scattering has helped uncover important fe…
