Magneto-oscillations in the Thermal Conductivity of Kitaev Magnet RuCl3
ORAL
Abstract
RuCl3 has been the subject of much intrigue and controversy due to it’s status as a possible realization of Kitaev’s honeycomb model and it’s exotic physics. Much of this attention has focused on the half-integer quantized thermal hall conductivity reported by Kasahara et al [1]. Here, we report a striking new observation in the system’s thermal transport physics. When cooled below 4K, RuCl3 exhibits strong magneto-oscillations in its longitudinal thermal conductivity. Additionally, the thermal conductivity follows a butterfly-shaped hysteresis loop that also displays oscillations. We discuss possible explanations for this surprising effect and provide updates on our attempts to reproduce the half-integer quantized thermal hall conductivity reported by Kasahara et al.
