论文摘要
多晶BA4NBIR3O12最近已被证明是有前途的旋转液体候选者。我们报告了一种简单可靠的方法，它可以通过BA4NB0.8IR3.2O12的实际化学计量生长这种基于三聚体的旋转液体候选材料的毫米大小的单晶。使用BACL2作为通量实现大晶体的生长。晶体显示出六角形板状习惯，边缘长达3毫米。该结构通过单晶体X射线衍射证实，发现与先前报道的BA12NB2.4IR9.6O36 [BA4NB0.8IR3.2O12]相同，实际上在3A位点的NB/IR占用率混合。对单个单晶的磁性和量热研究证实了旋转液态与最新报告一致的旋转液态的可能性
Polycrystalline Ba4NbIr3O12 has recently been shown to be a promising spin liquid candidate. We report an easy and reliable method to grow millimeter-sized single crystals of this trimer based spin liquid candidate material with the actual stoichiometry of Ba4Nb0.8Ir3.2O12. The growth of large crystals is achieved using BaCl2 as flux. The crystals show hexagonal plate-like habit with edges up to 3 mm in length. The structure is confirmed by single crystal X-ray diffraction and is found to be the same as of previously reported phase Ba12Nb2.4Ir9.6O36 [Ba4Nb0.8Ir3.2O12], indeed with a mixed occupancy of Nb/Ir at 3a site. The magnetic and calorimetric study on the individual single crystals confirms the possibility of a spin liquid state consistent with a recent report on a polycrystalline sample
