Orbital fluctuations in the S= 12 Mott insulator Sr2VO4
Abstract
We report a high-energy inelastic neutron-scattering study on Sr2VO4 that shows a transition from an orbital liquid phase at high temperature to an orbital-order phase at low temperature with an unquenched orbital angular momentum. Susceptibility under pressure shows a collapse of the magnetic phase transition due to enhanced orbital fluctuations. One possible explanation for our data is the recently proposed magnetically hidden order of …
