层状蜂窝晶格材料α-RuCl 3已经成为显示Kitaev量子自旋液体状态的主要候选者，因此吸引了许多研究兴趣。这里描述了一种新的RuI 3层状蜂窝晶格多晶型物，这种材料在化学和结构上与α-RuCl 3密切相关。该材料在适度升高的压力下合成，并且在环境条件下稳定。初步表征表明，它是一种金属导体，在0.35 K以下没有长程磁序，并且对热容有异常大的T线性贡献。该相具有层状蜂窝晶格和强自旋轨道耦合，为量子材料的表征提供了一条新的途径。
The layered honeycomb lattice material α‐RuCl3 has emerged as a prime candidate for displaying the Kitaev quantum spin liquid state, and as such has attracted much research interest. Here a new layered honeycomb lattice polymorph of RuI3, a material that is strongly chemically and structurally related to α‐RuCl3 is described. The material is synthesized at moderately elevated pressures and is stable under ambient conditions. Preliminary characterization reveals that it is a metallic conductor, with the absence of long‐range magnetic order down to 0.35 K and an unusually large T‐linear contribution to the heat capacity. It is proposed that this phase, with a layered honeycomb lattice and strong spin–orbit coupling, provides a new route for the characterization of quantum materials.
