论文摘要
磁性挫败感，交换相互作用之间的竞争通常会导致具有独特物理特性的新型磁接地态，这些磁接地状态可以取决于难以观察的相互作用的细节。当可以调整相互作用之间的平衡以访问多种类型的磁顺序时，此类状态特别有趣。我们提出鹿角，cu $ _3 $，因此$ _4 $（oh）$ _ 4 $，作为调整挫败感的潜在平台。与以前的报道相反，其三腿锯齿形梯子的低温磁态是最近提议在botallackite中表现出Spinon-Magnon混合的磁状态的准二维类似物。密度功能理论计算表明，鹿角的磁接地状态对原子位置的细节非常敏感，每个链条独立于相变的尖端，表明可调性的潜力很大。
Magnetic frustration, the competition among exchange interactions, often leads to novel magnetic ground states with unique physical properties which can hinge on details of interactions that are otherwise difficult to observe. Such states are particularly interesting when it is possible to tune the balance among the interactions to access multiple types of magnetic order. We present antlerite, Cu$_3$SO$_4$(OH)$_4$, as a potential platform for tuning frustration. Contrary to previous reports, the low-temperature magnetic state of its three-leg zigzag ladders is a quasi-one-dimensional analog of the magnetic state recently proposed to exhibit spinon-magnon mixing in botallackite. Density functional theory calculations indicate that antlerite's magnetic ground state is exquisitely sensitive to fine details of the atomic positions, with each chain independently on the cusp of a phase transition, indicating an excellent potential for tunability.
