Honeycomb Kitaev iridate and rhodate thin films — •Maximilian Uhl¹, Sebastian Esser¹, Vladimir Roddatis², Vasily Moshnyaga³, and Philipp Gegenwart¹ — ¹Experimentalphysik VI, Universität Augsburg, 86159 Augsburg, Germany — ²Institut für Materialphysik, Georg-August-Universität Göttingen, 37077 Göttingen, Germany — ³1.

Recently materials realizing the honeycomb Kitaev exchange attracted considerable attention (for a review see [1]). Li-based heavy transition metal oxides Li₂IrO₃ [2] and Li₂RhO₃ [3] are prototype systems in this class. For the latter material, up to now only polycrystals are available which display a spin-glassy ground state. Epitaxial thin films are thus of particular interest, as they could reveal the true ground state and its dependence on strain. We utilize the metal-organic aerosol deposition (MAD) technique [4] and report the successful growth of thin films of both materials, as well as their structural and magnetic characterization. This work is supported by the German Science Foundation through SPP 1666 and TRR 80.
