论文摘要
合成了具有OSXCL3的化学式（X = 0.81）的氯化物，并研究了其晶体结构和热力学特性。 OSXCL3在平均由OS离子部分占据的三角形晶格中以分层的CDCL2型结构结晶。然而，在显微镜长度尺度上，三角形晶格由纳米域组成，具有OS离子的蜂窝排列，如电子显微镜和拉曼散射实验所观察到的那样。磁化和热容量测量结果表明，没有磁性长阶降至0.08 K，而在0.15 K处的热容量的宽峰可能表明在局部蜂窝晶状体中的短距离顺序。 OSXCL3可能会表现出Kitaev旋转液体的某些方面，这些方面对于三氯化盐的蜂窝状晶格有望。
An osmium chloride with the chemical formula of OsxCl3 (x = 0.81) was synthesized and its crystal structure and thermodynamic properties were investigated. OsxCl3 crystallizes in a layered CdCl2-type structure with the triangular lattice partially occupied by Os ions on average. However, on microscopic length scales, the triangular lattice is composed of nano-domains with a honeycomb arrangement of Os ions, as observed by electron microscopy and Raman scattering experiments. Magnetization and heat capacity measurements revealed an absence of magnetic long-range order down to 0.08 K, while a broad peak in heat capacity at 0.15 K may indicate a short-range order in the local honeycomb lattice. OsxCl3 may exhibit certain aspects of the Kitaev spin liquid that are expected for a perfect honeycomb lattice of osmium trichloride.
