Long-wavelength correlations in ferromagnetic titanate pyrochlores as revealed by small angle neutron scattering
C. R. C. Buhariwalla, Q. Ma, L. Debeer-Schmitt +7
We have carried out small angle neutron scattering measurements on single crystals of two members of the family of cubic rare-earth titanate pyrochlores that display ferromagnetic…
Crystal field excitations from ions at defective sites in highly stuffed
Gabriele Sala, Dalini D. Maharaj, Matthew B. Stone +2
The pyrochlore magnet has been proposed as a quantum spin ice candidate, a spin liquid state expected to display emergent quantum electrodynamics with gauge photo…
Evidence for the Confinement of Magnetic Monopoles in Quantum Spin Ice
P. M. Sarte, A. A. Aczel, G. Ehlers +11
Magnetic monopoles are hypothesised elementary particles connected by Dirac strings that behave like infinitely thin solenoids. Despite decades of searches, free magnetic monopoles…
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…
Experimental Insights into Ground State Selection of Quantum XY Pyrochlores
Alannah M. Hallas, Jonathan Gaudet, Bruce D. Gaulin
Extensive experimental investigations of the magnetic structures and excitations in the XY pyrochlores have been carried out over the last decade. Three families of XY pyrochlores…
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…
