Single crystal growth of α-Li2IrO3 from separated educts — •Friedrich Freund, Anton Jesche, Ina-Marie Pietsch, and Philipp Gegenwart — EP VI, Center for Electronic Correlations and Magnetism, Augsburg University, 86159 Augsburg, Germany
Hexagonal iridates like α-Li2IrO3 are promising candidates for the realization of the Kitaev exchange interaction, which describes an anisotropic and bonding dependent interaction that can lead to novel types of spin liquid behavior. We report a method to grow for the first time single crystals of α-Li2IrO3. This method is using separated educts and could also be used to grow single crystals of other honeycomb transition metal oxides such as Li2RuO3. Besides the discussion of the new crystal growth method, we will present the structural and magnetic properties.
