Crystal and magnetic structures of Sr4MMn2O9 (M = Cu or Zn)

Abstract:

The crystal and magnetic structures of Sr4MMn2O 9 (M=Cu, Zn) have been refined from neutron powder diffraction data. These trigonal compounds (space group P321, a=9.5918(1), c=7.8114(1)Å (Cu); a=9.5894(1), c=7.5039(1)Å (Zn)) are n=3 members of the series A 3n+3MnBn+3O6n+9, with each unit cell containing three offset [001] polyhedral chains, each of which ideally contains a 1:1 ratio of B2O9 units and MO6 trigonal prisms. In fact anti-site disorder between Mn and M is observed, and for M=Cu th...
