Abstract

We study the transport and magnetic properties of hydrated and lithium-intercalated α-RuCl3,LixRuCl3·yH2O, to investigate the effect on mobile-carrier doping into candidate materials for a realization of a Kitaev model. From thermogravimetric and one-dimensional electron map analyses, we find two crystal structures of this system, that is, monolayer hydrated LixRuCl3·yH2O(x≈0.56,y≈1.3) and bilayer hydrated LixRuCl3·yH2O(x≈0.56,y≈3.9). The temperature dependence of the electrical resistivity shows a temperature hysteresis at 200-270 K, which is considered to relate to the formation of a charge order. The antiferromagnetic order at 7-13 K in pristine α-RuCl3 is successfully suppressed down to 2 K in bilayer hydrated LixRuCl3·yH2O, which is sensitive to not only the electronic state of Ru but also the interlayer distance between Ru-Cl planes.
