Determining the magnetic structure of novel binary oxide Ba7Mn4O15

Abstract: A novel binary oxide of manganese, Ba7Mn4O15 has been synthesised for the first time. It is of interest due to the dimer physics associate with the Mn2O9 face sharing octrahedra, low dimension spin order, and because of the potential for magnetoelectric coupling, recently highlighted in isostructural Sr7Mn4O15. Our provisional characterisation of Ba7Mn4O15 show a divergence between field-cooled and zero field-cooled magnetic susceptibility measurements at 50 K, indicating the onset of AFM magnetic ordering. We propose to perform a rapid access measurement on WISH to determine the nature of the magnetic ordering below this transition temperature. The results will contribute to broadening understanding of how crystal chemistry can be tuned to stabilise specific kinds of magnetic ordering and multiferroic couplings.
