论文摘要
在本手稿中，我们使用磁力显微镜尖端证明了超薄纳米模子中的Skyrmion形成。实验中使用了基于PT/CO/AU多层托管界面Dzyaloshiskii-Morya相互作用的亚微米大小。我们发现，由磁尖端产生的尖端场显着影响纳米模块的磁化状态，并导致天空的形成。微磁模拟解释了磁力显微镜扫描过程中磁态的演变，并确认了天际形成的可能性。在此过程中的关键转变是马蹄磁域的形成。我们发现，通过磁探针形成天空是一种可靠且重复的程序。我们的发现为纳米模特中的天空形成提供了简单的解决方案。
In this manuscript we demonstrate the skyrmion formation in ultrathin nanodots using magnetic force microscopy tip. Submicron-size dots based on Pt/Co/Au multilayers hosting interfacial Dzyaloshiskii-Morya interaction were used in the experiments. We have found that the tip field generated by the magnetic tip significantly affects the magnetization state of the nanodots and leads to the formation of skyrmions. Micromagnetic simulations explain the evolution of the magnetic state during magnetic force microscopy scans and confirm the possibility of the skyrmion formation. The key transition in this process is the formation of the horseshoe magnetic domain. We have found that formation of skyrmion by the magnetic probe is a reliable and repetitive procedure. Our findings provide a simple solution for skyrmions formation in nanodots.
