Effect on Local Structure and Phase Transition of Perovskite-Type [N(CH3)4]2Zn1-x Cu x Br4 (x = 0, 0.5, 0.7, and 1) Crystals with the Various Doping of Cu2+ Ions

Abstract This study focused on how the local structures in pure [N(CH3)4]2ZnBr4 crystal are affected by the partial replacement of Zn2+ ions with Cu2+ ions. The structures and phase transition temperatures TC of perovskite-type [N(CH3)4]2Zn1-x Cu x Br4 (x = 0, 0.5, 0.7, and 1) mixed crystals were al...
