采用SrCl 2助熔剂法合成了双钙钛矿结构的Sr 2NiWO 6单晶。这种高质量的前体使我们能够生长大的和相位纯的晶体，尺寸高达1 mm x 1 mm的基面和八面体形态。我们测量了沿着c轴和沿着oh平面的磁化强度的温度依赖性。数据的分析允许有效磁矩和居里-外斯温度的精确测定。Sr 2NiWO 6反铁磁性订单在T-N=54 K所揭示的磁化强度和比热数据。(C)2015年由Elsevier B. V.出版
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.
