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 Er $_{2} B_{2}$ O $_{7}$ , with $B =$ ~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…

Experimental evidence for field induced emergent clock anisotropies in the XY pyrochlore Er $_{2}$ Ti $_{2}$ O $_{7}$

J. Gaudet, A. M. Hallas, J. Thibault +3

The XY pyrochlore antiferromagnet Er $_{2}$ Ti $_{2}$ O $_{7}$ exhibits a rare case of $Z_{6}$ discrete symmetry breaking in its $ψ_{2}$ magnetic ground state. Despite being well-studied theoreti…
