论文摘要
磁性天空是局部的粒子样非平凡漩涡，在构建高性能拓扑设备方面有希望。 Skyrmionic设备中的读出功能需要将磁性天空转换为电信号。在这里，我们报告了对偶极气息的真实空间磁成像和各向异性磁化研究。使用Lorentz透射电子显微镜成像观察到单个Skyrmion链和单个Skyrmion。同时，同时获得了Fe3SN2纳米结构的各向异性磁场的田地，螺旋和天空计数的依赖性。我们的结果表明，天空的各向异性磁势与螺旋性无关，并且与天空计数成正比。我们的工作可以促进基于Skyrmion的Spintronic设备中的读出操作。
Magnetic skyrmions are localized particle-like nontrivial swirls that are promising in building high-performance topological spintronic devices. The read-out functions in skyrmionic devices require the translation of magnetic skyrmions to electrical signals. Here, we report combined real-space magnetic imaging and anisotropic magnetoresistance studies on dipolar skyrmions. A single skyrmion chain and single skyrmion are observed using Lorentz transmission electron microscopy imaging. Meanwhile, the field, helicity, and skyrmion count dependence of anisotropic magnetoresistance of the Fe3Sn2 nanostructures are obtained simultaneously. Our results demonstrate that the anisotropic magnetoresistance of skyrmions is independent of the helicity and proportional to the skyrmion count. Our work could promote read-out operations in skyrmion-based spintronic devices.
