Perovskite oxides exhibit a large array of interesting electronic properties. Owing to their difficult synthesis (requiring extremely high pressures) the MOsO3 Osmates offer a new frontier of exploration for this class of materials. LiOsO3 is a newly synthesised material, and preliminary measurements in the process of submission to Science indicate that it is a candidate for what P.W. Anderson proposed to call a ¿ferroelectric metal¿ i.e. a metallic solid which lacks a centre of inversion symmetry. The change in the susceptibility at Tc indicates that there is possibly a magnetic ordering of the osmium sublattice, coupled to the structural distortion. It would be of fundamental interest therefore to probe the possibility of either magnetic order or short-range correlations, and neutron diffraction using the WISH diffractometer at ISIS is an ideal strategy to probe such a possibility.
