Magnetic skyrmions are attracting interest as efficient information‐storage devices with low energy consumption, and have been experimentally and theoretically investigated in multilayers including ferromagnets, ferrimagnets, and antiferromagnets. The 3D spin texture of skyrmions demonstrated in ferromagnetic multilayers provides a powerful pathway for understanding the stabilization of ferromagnetic skyrmions. However, the manipulation mechanism of skyrmions in antiferromagnets is still lacking. A Hall balance with a ferromagnet/insulating spacer/ferromagnet structure is considered to be a promising candidate to study skyrmions in synthetic antiferromagnets. Here, high‐density Néel‐type skyrmions are experimentally observed at zero field and room temperature by Lorentz transmission electron microscopy in a Hall balance (core structure [Co/Pt]_n/NiO/[Co/Pt]_n) with interfacial canted magnetizations because of interlayer ferromagnetic/antiferromagnetic coupling between top and bottom [Co/Pt]_n multilayers, where the Co layers in [Co/Pt]_n are always ferromagnetically coupled. Micromagnetic simulations show that the generation and density of skyrmions are strongly dependent on interlayer exchange coupling (IEC) and easy‐axis orientation. Direct experimental evidence of skyrmions in synthetic antiferromagnets is provided, suggesting that the proposed approach offers a promising alternative mechanism for room‐temperature spintronics.

具有界面倾斜磁化的霍尔天平中的磁性天ization。

磁性天rm作为低能耗的高效信息存储设备吸引了人们的兴趣，并且已经在包括铁磁，铁磁和反铁磁在内的多层结构中进行了实验和理论研究。在铁磁多层膜中展示的Skyrmion的3D自旋纹理为了解铁磁Skyrmion的稳定性提供了强大的途径。但是，仍然缺乏反铁磁体中天体离子的操纵机制。具有铁磁体/绝缘垫片/铁磁体结构的霍尔平衡被认为是研究合成反铁磁体中的天空离子的有前途的候选人。在这里，通过霍尔天平的Lorentz透射电子显微镜在零场和室温下通过实验观察到了高密度Néel型天敌（核心结构[Co / Pt]_ñ /的NiO / [CO / PT] _Ñ）配有因为层间铁磁/反铁磁的顶部和底部之间的耦合[CO / PT]的界面倾斜的磁化_Ñ多层，其中在[CO / PT]的Co层_Ñ总是铁磁耦合。微观磁模拟表明，天体离子的产生和密度在很大程度上取决于层间交换耦合（IEC）和易轴取向。提供了合成反铁磁体中天空离子的直接实验证据，表明所提出的方法为室温自旋电子学提供了一种有希望的替代机制。
