Electronic devices of thin crystals of sodium iridate

POSTER

Abstract

Sodium iridate (Na2IrO3) is predicted to present exciting phenomena thanks to the honeycomb arrangement of its iridium ions and the interplay of electronic correlations and spin-orbit coupling, making it a close experimental incarnation of the Kitaev-Heisenberg model. Magnetic susceptibility and heat capacity measurements in this material have shown signature of magnetic ordered states [1]. Our Angle Resolved Photoemission Spectroscopy (ARPES) experiments have shown additionally the presence of a metallic feature near the Fermi energy, consistent with other experiments [2] identified as a surface state. Here we present electronic transport measurements on thin crystals of Na2IrO3 that aim to address and control magnetic ordered ground states in this material.
