Sodium Iridate (Na2IrO3) and Ruthenium Chloride (RuCl3) present exciting phenomena thanks to the honeycomb arrangement of their ions and the interplay of electronic correlations and spin-orbit coupling. They constitute a close experimental realization of the the Kitaev-Heisenberg model. Magnetic susceptibility and heat capacity measurements in bulk crystals have shown signature of magnetic ordered states [1]. We have integrated exfoliated thin crystals of Na2IrO3 and RuCl3 into an electronic device and performed electronic transport measurements, finding through temperature dependent resistance measurements anomalies that correspond to the magnetic ordered transition for Na2IrO3.
