Magnetic hybrid organic-inorganic perovskite (CH3NH3)2XCl4 (X = Mn, Cu, Co) crystals

For the hybrid organic-inorganic perovskites with the general formula of A(2)M(II)X(4) (A = methylammonium; M-II = Mn, Cu and Co; X = Cl), the arrangement of metal ions and organic ligands leads to a delicate balance of space, spin and charge, which results in diverse properties. In this paper, we reported a group of hybrid organic-inorganic perovskite single crystals of (CH3NH3)(2)MnCl4, (CH3NH3)(2)CuCl4 and (CH3NH3)(2)CoCl4 grown by a simple solution evaporation method. Magnetic measurements show that all the single crystals display magnetic ordering at low temperature. Our results reveal a novel group of hybrid organic-inorganic magnetic perovskites.
