The new ordered double perovskite SrLaCuIrO6

Abstract The new fully rock-salt ordered Ir 5+ double perovskite SrLaCuIrO 6 was synthesized, and its structural, magnetic and electronic properties were investigated. The compound crystallizes tetragonally (space group I 4/ m ). The Cu 2+ cation leads to strong Jahn-Teller distortion of the CuO 6 octahedra. The compound shows semiconducting behavior with an estimated band gap of approximately 0.2 eV. At around 10 K a magnetic transition is observed.
