论文摘要
二维磁性材料的高可调性（通过应变，门控，异质结构或其他方式）为研究多功能磁性和控制紧急磁相提供了独特的条件。扩大此类材料中可实现的磁现象的范围对于基本和技术进步都很重要。在这里，我们执行原子自旋动力学模拟，以探索原子单层的（手性）磁相，处于被抑制的第一近骨交换相互作用的极限。我们报告了针对正方形和蜂窝晶状体对称性获得的外来磁性构型的丰富相图，包括铁磁和抗铁磁型自旋 - 细胞相对性以及多种类型的磁性天空。我们对Skyrmion崩溃进行了最小能量路径分析，以评估此类拓扑对象的稳定性，并揭示磁性单层可能是候选者，可以容纳迄今为止在实验上回避的反铁磁天空。
High tunability of two dimensional magnetic materials (by strain, gating, heterostructuring or otherwise) provides unique conditions for studying versatile magnetic properties and controlling emergent magnetic phases. Expanding the scope of achievable magnetic phenomena in such materials is important for both fundamental and technological advances. Here we perform atomistic spin-dynamics simulations to explore the (chiral) magnetic phases of atomic monolayers in the limit of suppressed first-neighbors exchange interaction. We report the rich phase diagram of exotic magnetic configurations, obtained for both square and honeycomb lattice symmetries, comprising coexistence of ferromagnetic and antiferromagnetic spin-cycloids, as well as multiple types of magnetic skyrmions. We perform a minimum-energy path analysis for the skyrmion collapse to evaluate the stability of such topological objects, and reveal that magnetic monolayers could be good candidates to host the antiferromagnetic skyrmions that are experimentally evasive to date.
