Spectrum of new 3-dimensional Quantum Magnet formed from triangular and hexagonal units

Quantum magnets formed from spin-1/2 ions, show a range of exotic phenomena such as quantum critical scaling and spinon excitations as found in one-dimensional antiferromagnets, gapped excitations due to spin pairing in dimerized magnets and coherently fluctuating ground states as in frustrated quantum spin liquids. Here we wish to investigate the magnetic properties of a unique cubic quantum magnet Cu3WO6, which consists of a three-dimensional arrangement or hexagons coupled by triangles and which does not develop long-range magnetic order even down to lowest temperatures.

由自旋1/2离子构成的量子磁体，可展现出一系列新奇物理现象，包括一维反铁磁体中观测到的量子临界标度（quantum critical scaling）与自旋子激发（spinon excitations）、二聚化磁体中因自旋配对产生的有隙激发，以及阻挫量子自旋液体（frustrated quantum spin liquids）中存在的相干涨落基态。本研究旨在探究一款独特的立方量子磁体Cu3WO6的磁学特性，该材料采用三维六边形结构排布，六边形单元间通过三角形结构实现耦合，即便在最低实验温度下也不会形成长程磁有序（long-range magnetic order）。
