Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state.

ABSTRACT: Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electric transport. In insulating quantum magnetic materials, the effects of disorder are less understood and can drastically impact fluctuating spin states like quantum spin liquids. In the absence of transport tools, disorder is typically characterized using chemical methods or by semi-classical modeling of spin dynamics. This requires high magnetic fields that may not always be accessible. Here, we show that magnetization plateaus-incompressible states found in many quantum magnets-provide an exquisite platform to uncover small amounts of disorder, regardless of the origin of the plateau.
