Exploring the influence of disorder on magnetic moment fragmentation
ORAL
Abstract
Recent neutron scattering measurements demonstrating concurrent all-in-all-out antiferromagnetic order and pinch-point diffuse scattering in the pyrochlore Nd2Zr2O7 provide compelling evidence for the phenomenon of magnetic moment fragmentation1. However, the influence of chemical and crystallographic disorder native to the pyrochlore lattice on the formation of this underlying state remains poorly understood. Here we present an experimental exploration of the role of native disorder on the features associated with spin fragmentation in Nd2Zr2O7. Neutron scattering and thermodynamic measurements of crystals with varying defect concentrations, examined by electron microprobe analysis, are studied to resolve the impact of disorder on the ground state of this material.
