Magnetic skyrmions are chiral spin magnetization structures with topological properties and have attracted great interest due to their small size and extremely low manipulation current density in the next generation spintronic devices. In this work, we introduced skyrmion into the magnetic tunnel junction and designed a dumbbell-shaped microwave detector based on skyrmion. It has a very high sensitivity, reaching more than 280000 mV/mW without any external bias field. Moreover, we expand this dumbbell-shaped detector into an array combination, which is expected to increase its sensitivity. Our studies may present guidance for the design of skyrmion based microwave detectors.

磁性斯格明子是具有拓扑特性的手性自旋磁化结构，由于其在下一代自旋电子器件中的小尺寸和极低的操纵电流密度而引起了极大的兴趣。在这项工作中，我们将斯格明子引入磁隧道结，并基于斯格明子设计了一个哑铃形微波探测器。它具有非常高的灵敏度，无需任何外部偏置场即可达到 280000 mV/mW 以上。此外，我们将这种哑铃形探测器扩展为阵列组合，有望提高其灵敏度。我们的研究可为基于斯格明子的微波探测器的设计提供指导。
