RT Journal Article T1 Mn3MnNb2O9: high-pressure triple perovskite with 1 : 2 B-site order and modulated spins A1 Solana Madruga, Elena A1 Aguilar Maldonado, Cintli A1 Arévalo López, Ángel M. A1 Attfield, J. Paul A1 Mentré, Olivier A1 Ritter, Clemens AB The first triple perovskite with Mn in A- and 1 : 2 B-site order Mn3MnNb2O9, prepared using high pressure phase transformation of the magnetodielectric Mn4Nb2O9, is reported herein. It has a complex magnetic behaviour with a transition from a collinear AFM into an evolving incommensurate spin density wave (SDW) further stabilised into a lock-in structure dictated by the B-site order.
