Over the past two decades, significant progress in two-dimensional (2D) materials has invigorated research in condensed matter and material physics in low dimensions. While traditionally studied in three-dimensional systems, magnetism has now been extended to the 2D realm. Recent breakthroughs in 2D magnetism have attracted substantial interest from the scientific community, owing to the stable magnetic order achievable in atomically thin layers of the van der Waals (vdW)-type layered magnetic materials. These advances offer an exciting platform for investigating related phenomena in low dimensions and hold promise for spintronic applications. Consequently, vdW magnetic materials with tunable magnetism have attracted significant attention. Specifically, antiferromagnetic metal thiophosphates MPX (M = transition metal, P = phosphorus, X = chalcogen) have been investigated extensively. These materials exhibit long-range magnetic order spanning from bulk to the 2D limit. The magnetism in MPX arises from localized moments associated with transition metal ions, making it tunable substitutions and intercalations. In this review, we focus on such tuning by providing a comprehensive summary of various metal- and chalcogen-substitution and intercalation studies, along with the mechanism of magnetism modulation, and a perspective on the development of this emergent material family.
在过去二十年中，二维（2D）材料的重大进展激发了低维凝聚态物质与材料物理学的研究。磁性虽然传统上是在三维系统中研究，但现在已扩展到二维领域。二维磁性领域的近期突破引起了科学界的广泛关注，这是由于在范德华（vdW）型层状磁性材料的原子薄层中可实现稳定的磁序。这些进展为研究低维相关现象提供了一个令人兴奋的平台，并有望应用于自旋电子学。因此，具有可调磁性的vdW磁性材料备受关注。具体而言，反铁磁金属硫代磷酸盐MPX（M = 过渡金属，P = 磷，X = 硫族元素）已得到广泛研究。这些材料展现出从体相到二维极限的长程磁序。MPX中的磁性源于与过渡金属离子相关的局域磁矩，这使得通过取代和插层实现磁性可调成为可能。在本综述中，我们通过全面总结各种金属和硫族元素取代及插层研究、磁调制机制以及对这个新兴材料家族发展的展望，来聚焦于这种磁性调控。
