摘要
在最近一篇关于LiCuO磁性的工作中，Shu等人[New J. Phys. 19 (2017) 023026]提出了一个“简化”的无阻挫微观模型，该模型与过去几十年通过大量工作精炼出的模型有显著差异。我们表明，所提出的模型与已知的实验数据不一致，包括报道的直到550 K的磁化率数据。利用的8阶高温展开，我们表明LiCuO的实验数据与先前基于非弹性中子散射（INS）研究得出的模型一致。我们还建立了真实阻挫磁系统Curie-Weiss定律有效的温度范围。我们认为，仅知道时的长程有序磁结构以及有限温度范围内的，不足以提取阻挫磁体中所有相关的耦合；还必须使用饱和场和INS数据来确定多个交换耦合，包括微弱但起决定性作用的阻挫反铁磁（AFM）链间耦合。
