Solving the magnetic structure of ruthenium based 2H-perovskites

Abstract: The variant of the Hexagonal perovskite oxides are characterised by chains of trigonal prisms and octahedra, leading to a number of fascinating properties. Using resonant x-ray scattering we have determined the propagation vector of two ruthenates Sr3ARuO6(A=Li,Na). We have also omitted one of the three possible symmetric sub-groups that can explain the system?s magnetic structure. We now need to determine the moment orientation to fully solve the magnetic structure. Using the Wish diffractometer we propose to use the sensitivity of neutrons to the orientation of magnetic moments to quickly identify the correct magnetic ground states of these systems. The Li compound exhibits a previously unreported transition, not visible in specific heat measurements and barely visible in magnetisation measurements. Magnetic neutron scattering will allow us to distinguish the cause of this transition.
