Electronic transport in thin crystals of ruthenium chloride

POSTER

Abstract

Ruthenium chloride (RuCl3) is a layered material where crystal field effects, electronic correlations and spin-orbit coupling give rise to a Mott insulator with spin-orbit coupled moments arranged in a honeycomb lattice with bond-directional interactions. The ensemble of these features makes this material a very close experimental realization of the Kitaev-Heisenberg model. Exciting ground states have been predicted for this system, such as quantum spin liquids, consistent with recent inelastic neutron scattering experiments [1] as well as long ranged magnetic ordered states [2]. Here we present preliminary electronic transport experiments on thin crystals of RuCl3 as well as the band structure of this material through Angle resolved Photoemission Spectroscopy ARPES measurements and the effects of electrostatic doping.
