Magnetic Structure of the double charge ordered multiferroic perovskites HgMn7O12

Abstract: Understanding the magnetic structure of the perovskite manganites has been a significant field of research over the past 20 year due of their numerous technologically relevant properties. More recently, 134-perovskite have been of great interest on account of their multiferroicity, and understanding the magnetic structure is key in elucidating the magnetoelectric coupling mechanisms. We request 1 day on WISH to study the magnetic Bragg scattering in novel HgMn3Mn4O12 in an attempt to learn more about the fundamental mechanism behind the pronounced magnetoelectric coupling that we have observed. Contrary to other 134 family member, the charge and orbital ordered ground state is unique and resolves itself through a charge transfer and A and B-site orbitally order ferroelectric ground state. The magnetoelectric coupling is hence distinct form other 134-system and requires further study.
