摘要:

过去二十年间,二维(2D)材料的重要进展推动了低维凝聚态物理与材料物理的研究。磁性传统上在三维体系中被研究,如今已拓展至二维领域。二维磁性方面的最新突破引起了科学界的广泛关注,这是因为在范德华(vdW)型层状磁性材料的原子级薄层中可以实现稳定的磁有序。这些进展为研究低维相关现象提供了令人兴奋的平台,并有望用于自旋电子学应用。因此,具有可调磁性的vdW磁性材料受到了极大关注。具体而言,反铁磁金属硫代磷酸盐MPX3(M = 过渡金属,P = 磷,X = 硫族元素)已被广泛研究。这些材料表现出从体相到二维极限的长程磁有序。MPX3中的磁性来源于与过渡金属离子相关的局域磁矩,使其可以通过取代和插层进行调控。在这篇综述中,我们聚焦于此类调控,全面总结了各种金属和硫族元素取代及插层研究,以及磁性调控机制,并对这一新兴材料家族的发展进行了展望。

英文摘要:

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 captured 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 MPX3 (M = transition metal, P = phosphorus, X = chalcogen) have been investigated extensively. These materials exhibit long-range magnetic orders spanning from bulk to the 2D limit. The magnetism in MPX3 arises from localized moments associated with transition metal ions, making it tunable via 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.
