Effect of Chemical Pressure on the Crystal Electric Field States of Erbium Pyrochlore Magnets
J. Gaudet, A. M. Hallas, A. I. Kolesnikov +1
We have carried out a systematic study of the crystal electric field excitations in the family of cubic pyrochlores ErO, with ~Ti, Ge, Pt, and Sn, using neutron spec…
Phase Competition in the Palmer-Chalker XY Pyrochlore ErPtO
A. M. Hallas, J. Gaudet, N. P. Butch +5
We report neutron scattering measurements on ErPtO, a new addition to the XY family of frustrated pyrochlore magnets. Symmetry analysis of our elastic scattering data s…
Universal Dynamic Magnetism in Yb-Pyrochlores with Disparate Ground States
A. M. Hallas, J. Gaudet, N. P. Butch +5
The ytterbium pyrochlore magnets, Yb2B2O7 (B = Sn, Ti, Ge) are well described by S_eff = 1/2 quantum spins decorating a network of corner-sharing tetrahedra and interacting via ani…
XY Antiferromagnetic Ground State in the Effective S=1/2 Pyrochlore Yb2Ge2O7
A. M. Hallas, J. Gaudet, M. N. Wilson +10
We report neutron scattering and muon spin relaxation measurements (muSR) on the pyrochlore antiferromagnet Yb2Ge2O7. Inelastic neutron scattering was used to probe the transitions…
