摘要:

强阻挫系统中的自旋因涌现包括超导和量子自旋液体在内的奇特量子态而备受关注。本文报告了在averievite CsClCu5P2O10单晶中发现级联相变与巨大磁各向异性。在零场下,CsClCu5P2O10在约225 K发生一级结构相变,从高温中心对称P-3m1转变为低温非中心对称P321;随后在13.6 K发生AFM转变,在约3 K发生另一次结构相变,并在约2.18 K发生另一次AFM转变。基于磁场垂直于ab平面的磁化率和磁化强度数据,构建了相图,包含顺磁态、两个AFM态和四个场诱导态(含两个磁化平台)。研究结果表明,准二维CsClCu5P2O10展现出丰富的结构与变磁性转变,averievite家族是探索新奇量子态的沃土。

英文摘要:

Spins in strongly frustrated systems are of intense interest due to the emergence of intriguing quantum states including superconductivity and quantum spin liquid. Herein we report the discovery of cascade of phase transitions and large magnetic anisotropy in the averievite CsClCu5P2O10 single crystals. Under zero field, CsClCu5P2O10 undergoes a first-order structural transition at around 225 K from high temperature centrosymmetric P-3m1 to low temperature noncentrosymmetric P321, followed by an AFM transition at 13.6 K, another structural transition centering at ~3 K, and another AFM transition at ~2.18 K. Based upon magnetic susceptibility and magnetization data with magnetic fields perpendicular to the ab plane, a phase diagram, consisting of a paramagnetic state, two AFM states and four field-induced states including two magnetization plateaus, has been constructed. Our findings demonstrate that the quasi-2D CsClCu5P2O10 exhibits rich structural and metamagnetic transitions and the averievite family is a fertile platform for exploring novel quantum states.
