On cooling below 30 K, the κ-(ET)₂Hg(SCN)₂Cl quasi-two-dimensional organic metal, which is in the quantum spin liquid state at liquid helium temperatures, undergoes a transition to the Mott insulator state. The application of a hydrostatic pressure p = 0.7 kbar stabilizes the metallic state and makes it possible to study the behavior of the interlayer magnetoresistance at liquid helium temperatures. The field dependence of the magnetoresistance exhibits an unlimited power-law growth, which indicates that the polaron mechanism contributes to the interlayer transport. The spectrum of observed magnetoresistance oscillations corresponds to the Fermi surfaces characteristic of conducting layers with the κ-type structure.

在冷却到30 K以下时，在液氦温度下处于量子自旋液态的κ-（ET）₂ Hg（SCN）₂ Cl准二维有机金属经历了向Mott绝缘子态的转变。静水压力p = 0.7 kbar的施加使金属状态稳定，并使研究液氦温度下层间磁阻的行为成为可能。磁阻的场依赖性表现出无限的幂律增长，这表明极化子机制有助于层间传输。观察到的磁阻振荡的频谱对应于具有κ型结构的导电层的费米表面特性。
