Abstract
Complex magnetic ordering such as meta-magnetism and skyrmions is attractive for its potential applications in spintronics and fundamental understanding of magnetism. However, complex magnetic ordering is rarely observed in intrinsic van der Waals layered materials, limiting the exploration of two-dimensional (2D) magnetism. Here, we successfully synthesized a novel compound, Cu2xFe1−xPS3, which represents the first meta-magnetic van der Waals material with field-induced ferromagnetism. In this compound, monovalent Cu partially replaces the Fe positions in the FePS3 lattice in the form of dimers. The substitution of Cu breaks the 2D Ising antiferromagnetic structure, resulting in the complex coexistence of weak ferromagnetism and antiferromagnetism. Importantly, field-induced ferromagnetism is observed when the external magnetic field is perpendicular to the ab plane of the material. The nature of the meta-magnetic transition is attributed to the uncompensated antiferromagnetism with noncollinear magnetic structure under external magnetic field. Our work paves the way to realize 2D complex magnetic ordering.
摘要
复杂的磁有序, 如介磁性和斯格明子, 因其在自旋电子学中的潜在应用和对磁性的基本认知的意义而广受关注. 然而,在本征范德华层状材料中很少观察到复杂的磁有序, 这限制了二维磁性在该领域的探索. 本文报道了一种新的化合物Cu2xFe1−xPS3, 它是第一种具有场诱导铁磁性的介磁范德华层状材料. 在该化合物中, 单价Cu以二聚体的形式部分取代FePS3晶格中Fe的位置. Cu的取代破坏了FePS3的二维伊辛反铁磁结构, 导致弱铁磁性和反铁磁性共存. 更重要的是, 当外磁场垂直于材料的ab平面时, 我们可以观察到场诱导的铁磁性. 此材料的介磁相变本质归因于未补偿反铁磁结构在外磁场下转变为非共线磁结构. 我们的工作为实现二维介磁有序化提供了一条道路.
