Magnetic skyrmions are promising as next-generation information units. Their antiparticle—the antiskyrmion—has also been discovered in chiral magnets. Here we experimentally demonstrate antiskyrmion sliding in response to a pulsed electric current at room temperature without the requirement of an external magnetic field. This is realized by embedding antiskyrmions in helical stripe domains, which naturally provide one-dimensional straight tracks along which antiskyrmion sliding can be easily launched with low current density and without transverse deflection from the antiskyrmion Hall effect. The higher mobility of the antiskyrmions in the background of helical stripes in contrast to the typical ferromagnetic state is a result of intrinsic material parameters and elastic energy of the stripe domain, thereby smearing out the random pinning potential, as supported by micromagnetic simulations. The demonstration and comprehensive understanding of antiskyrmion movement along naturally straight tracks offers a new perspective for (anti)skyrmion application in spintronics.

磁性斯格明子有望成为下一代信息单元。它们的反粒子——反斯格明子——也在手性磁体中被发现。在这里，我们通过实验证明了在室温下响应脉冲电流而无需外部磁场的反斯格明子滑动。这是通过将反斯格明子嵌入螺旋条纹域中来实现的，螺旋条纹域自然地提供一维直线轨道，沿着该轨道可以以低电流密度轻松地启动反斯格明子滑动，并且不会因反斯格明子霍尔效应而产生横向偏转。与典型的铁磁态相比，螺旋条纹背景中反斯格明子的较高迁移率是条纹域的固有材料参数和弹性能的结果，从而消除了随机钉扎势，正如微磁模拟所支持的那样。对反斯格明子沿自然直线轨道运动的演示和全面理解为（反）斯格明子在自旋电子学中的应用提供了新的视角。
