dc.description.abstractTransition metal oxides that are capable of intercalating small mobile ions such as Li+ and Na+ have been intensively studied for their electrochemical properties, but their magnetic properties remain relatively unexplored. Those with CdI2-type oxide layers such as LiCoO2, which are the most interesting for metal-ion battery cathode applications, have quasi two-dimensional triangular arrays of transition metals which are not conducive to long-range magnetic ordering (although they still show interesting properties, the most notable example being the superconductor NaxCoO2.yH2O). When these compounds are modified so that 1/3 of the transition metal sites contain nonmagnetic cations, an ordered hexagonal honeycomb lattice can result. This topology does support long-range magnetic order of various types, including antiferromagnetic (AFM) structures. A significant number of such compounds have been reported, and where magnetic properties have been measured, many of them show evidence for long-range AFM ordering. Here, we present the results of the first low-temperature neutron diffraction studies of long-range magnetic structure for a series of honeycomb compounds with Te6+ or Sb5+ as the non-magnetic cation. The work presented will focus on P2-type (rather than the more common O3-type) layered compounds.en_AU
