论文摘要
挫折的一维一维量子磁铁CS $ _ {2} $ cu $ _ {2} $ mo $ $ $ $ $ _ {3} $ o $ $ _ {12} $的单一晶体样本是通过磁性和热力学测量值调查的。无论晶体方向如何,饱和场以下出现了一个新阶段。建议预饱和阶段代表自旋 - 纽扣秩序或其他多麦克努族冷凝物。对于每个几何,远程有序圆顶内的相图在质量上都不同。特别是,沿链方向的场中确定了多个跃迁。
A single-crystal sample of the frustrated quasi one-dimensional quantum magnet Cs$_{2}$Cu$_{2}$Mo$_{3}$O$_{12}$ is investigated by magnetic and thermodynamic measurements.A combination of specific heat and magnetic torque measurements maps out the entire $H$-$T$ phase diagram for three orientations.Remarkably, a new phase emerges below the saturation field, irrespective of the crystal orientation. It is suggested that the presaturation phase represents spin-nematic order or other multi-magnon condensate. The phase diagrams within the long-range ordered dome are qualitatively different for each geometry. In particular, multiple transitions are identified in the field along the chain direction.
