论文摘要
磁性天空是作为纳米级信息载体具有巨大潜力的拓扑自旋纹理。最近，在抗铁磁铁中预测了天际，在稳定性，大小和动力学特性方面具有关键优势，而不是其铁磁类似物。但是，他们的实验演示仍然缺乏。在这里，我们使用交换偏置在室温和零外部磁场上显示了从铁磁天空中的烙印到IRMN抗fiferromagnet的薄膜。使用高空间 - 分辨率X射线磁圆二色性光发射电子显微镜（XMCD-eem），我们观察到IRMN内部的印迹旋转纹理从XMCD信号中的XMCD信号与非补偿的MN旋转的界面上的XMCD信号与Ferromagnet。此结果为基于抗铁磁体中的Skyrmion操纵而开辟了逻辑和内存设备的路径。
Magnetic skyrmions are topological spin textures holding great potential as nanoscale information carriers. Recently, skyrmions have been predicted in antiferromagnets, with key advantages in terms of stability, size, and dynamical properties over their ferromagnetic analogs. However, their experimental demonstration is still lacking. Here, we show the imprint from ferromagnetic skyrmions into a thin film of an IrMn antiferromagnet, at room temperature and zero external magnetic field, using exchange-bias. Using high-spatial-resolution x-ray magnetic circular dichroism photoemission electron microscopy (XMCD-PEEM), we observed the imprinted spin textures within the IrMn from the XMCD signal of the uncompensated Mn spins at the interface with the ferromagnet. This result opens up a path for logic and memory devices based on skyrmion manipulation in antiferromagnets.
