Crystal structure and magnetic properties of 5d double perovskite oxide Sr2EuOsO6

Polycrystalline Sr2EuOsO6 has been synthesized with high-pressures and temperatures. It crystallizes in a monoclinic double perovskite structure and shows an antiferromagnetic-like transition at 51 K in a magnetic susceptibility measurement. The transition has been further characterized by specific measurements and electrical resistivity measurements. The results are compared with the magnetic properties of Ba2EuOsO6 [1] and other double perovskite oxides containing Os(V) atom. We will discuss role of spin-orbit coupling and spin polarization on the gapped electronic structure of Sr2EuOsO6 and other related compounds.\\[4pt] [1] Y. Hinatsu et al. J.
