Abstract

We present a neutron and x-ray scattering investigation of Ca3LiOsO6, a material that has been predicted to host magnetic ordering through an extended superexchange pathway involving two anions. Despite the apparent 1D nature and triangular units of magnetic osmium ions the onset of magnetic correlations has been observed at a high temperature of 117 K in bulk measurements. We experimentally determine the magnetically ordered structure and show it to be long range and three dimensional. Our results support the model of extended superexchange interaction.
