Spin-liquid physics of CuIrO3 and ZnIrO3

We seek to explore the spin dynamics and the tentative spin-liquid phase in our newly discovered compounds ZnIrO3 and CuIrO3, which are chemical modification of beta-Li2IrO3 (frustrated Kitaev magnet). Our thermodynamic measurements reveal the absence of long-range magnetic ordering in both componds down to at least 1.8 K. Using muons as a powerful method for investigating frustrated systems, we want to to explore the ground state of ZnIrO3 and CuIrO3 and reveal details of spin dynamics in it or detect the coexistence of dynamic and static spins and quantify their ratio.

本研究旨在探究我们新发现的ZnIrO3与CuIrO3化合物中的自旋动力学（spin dynamics）及疑似自旋液体相（spin-liquid phase）；这两种化合物均为β-Li2IrO3（受挫Kitaev磁体(frustrated Kitaev magnet)）的化学修饰体系。我们的热力学测量结果显示，两种化合物在低至1.8 K的温度范围内均未出现长程磁有序（long-range magnetic ordering）。本研究将采用μ子（muons）作为探究受挫系统的有效手段，旨在探明ZnIrO3与CuIrO3的基态（ground state），揭示其中自旋动力学的细节，或是检测动态自旋（dynamic spins）与静态自旋（static spins）的共存状态并量化二者的占比。
