论文摘要
由于磁性和拓扑之间的相互作用，拓扑自旋纹理（例如Skyrmion Crystal）是异常物理现象的来源。由于物理现象取决于拓扑特性和基础旋转结构的对称性，因此寻找新的拓扑旋转纹理和新兴现象是凝结物理学的挑战之一。在这封信中，我们从理论上探索了巡回磁铁中的旋转，电荷和自由度自由度之间的协同作用，这引起了新的拓扑旋转纹理。通过对蜂窝亲块晶格模型的有效自旋模型进行模拟退火，我们在低温下发现了众多的Skyrmion Crystal Immantibisitions，其拓扑旋转纹理分为三种类型：铁，抗毒素，抗毒药和铁甲状腺素层晶体水晶。我们表明，所获得的Skyrmion晶体是无自旋轨道偶联蜂窝结构的结果。我们的结果揭示了巡回蜂窝磁铁具有多种SKX和新兴现象的潜力。
Topological spin textures, such as a skyrmion crystal, are a source of unusual physical phenomena owing to the interplay between magnetism and topology. Since physical phenomena depend on the topological property and the symmetry of underlying spin structures, the search for new topological spin textures and emergent phenomena is one of the challenges in condensed matter physics. In this letter, we theoretically explore new topological spin textures arising from the synergy between spin, charge, and sublattice degrees of freedom in an itinerant magnet. By performing simulated annealing for an effective spin model of the honeycomb Kondo lattice model, we find a plethora of skyrmion crystal instabilities at low temperatures, whose topological spin textures are classified into three types: ferrochiral, antiferrochiral, and ferrichiral skyrmion crystals. We show that the obtained skyrmion crystals are the consequence of the spin-orbit-coupling-free honeycomb structure. Our results reveal the potential for itinerant honeycomb magnets to host a wide variety of SkXs and emergent phenomena.
