Single crystals of the double perovskite Sr2NiWO6 were synthesized via SrCl2 flux growth using high quality, phase-pure polycrystalline Sr2NiWO6 as precursor material. This high quality precursor enabled us to grow large and phase pure crystals with sizes up to 1 mm x 1 mm in the basal plane and octahedral morphology. We measured the temperature dependence of the magnetization along the c-axis and along the oh plane. The analysis of the data allows a precise determination of the effective magnetic moment and the Curie-Weiss temperature. Sr2NiWO6 orders antiferromagnetically at T-N=54 K as revealed by magnetization and specific heat data. (C) 2015 Published by Elsevier B.V.
