Temperature-dependent crystal structure analysis of new pyrochlore ruthenate In2Ru2O7

Abstract: In search for new materials with exotic electronic states, one often turns to strongly correlated materials. Ruthenium oxides attract attention as they exhibit intriguing phenomena such as unconventional superconductivity, metal-to-insulator transition or complex spin-orbital order. We synthesised a new pyrochlore ruthenate In2Ru2O7, which at 232 K shows a suppression of magnetisation to nearly zero. This behaviour is similar to some other ruthenates where spin-singlet formation appears by accompanying a structural transition. X-ray diffraction shows symmetry lowering with decreasing temperature. In order to understand the transition and the ground state in this material, detailed structural data is necessary. However, determination of oxygen positions by X-ray diffraction remains elusive. We would like to investigate the structural transition using powder neutron diffraction at HRPD.
