Magnetic dilution and domain selection in the XY pyrochlore antiferromagnet ErTiO
J. Gaudet, A. M. Hallas, D. D. Maharaj +7
Below K, the XY pyrochlore ErTiO orders into a non-collinear, antiferromagnetic structure referred to as the state. The magnetic order in ErT…
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…
Gapless quantum excitations from an Ice-like Splayed Ferromagnetic ground state in stoichiometric Yb2Ti2O7
J. Gaudet, K. A. Ross, E. Kermarrec +4
The ground state of the quantum spin ice candidate magnet Yb2Ti2O7 is known to be sensitive to weak disorder at the 1 percent level which occurs in single crystals grown from the m…
