Copper-oxide-based high-temperature superconductors have complex phase diagrams with multiple ordered phases. It even appears that the highest superconducting transition temperatures for certain cuprates are found in samples that display simultaneous onset of magnetism and superconductivity. We show here how the thermodynamics of fluid mixtures-a touchstone for chemistry as well as hard and soft condensed matter physics-accounts for this startling observation, as well as many other properties of the cuprates in the vicinity of the instability toward "striped" magnetism.
基于氧化铜的高温超导体具有包含多个有序相的复杂相图。甚至似乎某些铜酸盐的最高超导转变温度出现在同时出现磁性和超导性的样品中。我们在此展示了流体混合物的热力学——化学以及硬凝聚态和软凝聚态物理的试金石——如何解释这一惊人的观察结果,以及铜酸盐在趋向“条纹”磁性的不稳定性附近的许多其他性质。
