论文摘要
控制和理解天空的团结对于实现未来技术很重要。特别是，与磁空的2D晶格相关的顺序diSorder转变可能会对运输和其他动态功能产生重大影响。迄今为止，Skyrmion合奏主要在散装晶体中研究，或者是薄膜设备中的孤立的天空。在这里，我们研究了在室温和极地范德华磁体中零场在零场处的凝结。我们证明，我们可以通过$ $ m尺度上的结构限制来设计有序的Skyrmion晶体，从而在与设备应用相关的尺度上进行了对此订单级别过渡的控制。
Control and understanding of ensembles of skyrmions is important for realization of future technologies. In particular, the order-disorder transition associated with the 2D lattice of magnetic skyrmions can have significant implications for transport and other dynamic functionalities. To date, skyrmion ensembles have been primarily studied in bulk crystals, or as isolated skyrmions in thin film devices. Here, we investigate the condensation of the skyrmion phase at room temperature and zero field in a polar, Van der Waals magnet. We demonstrate that we can engineer an ordered skyrmion crystal through structural confinement on the $μ$m scale, showing control over this order-disorder transition on scales relevant for device applications.
