手性自旋织构，如磁skyrmion和畴壁，吸引了广泛的研究，由于它们可能在自旋电子学技术的应用1。特别是Skyrmions是二进制信息载体的有力候选者，如赛道存储器2。它们是拓扑稳定的，空间紧凑的，很容易被电流驱动3，4。然而，skyrmion通常仅在相空间的有限区域中稳定-即，在一定的温度和外加的外场下。为了实现其在自旋电子技术中的潜力，Skyrmions必须在商业上可行的条件下稳定：室温，零外加场，以及一系列物理几何形状。Skyrmions已经在破坏反演对称性的情况下进行了原型研究，例如非中心对称的块状磁体，并且这些反演对称性与共线相互作用竞争，如稳定的旋转自旋操纵界面DM相互作用7，在室温下创建定制的Skyrmions，并且没有应用
Chiral spin textures like magnetic skyrmions and domain walls have attracted extensive study due to their possible applications in spintronics technologies1. Skyrmions in particular are a strong candidate for binary information carriers in technologies like racetrack memory2. They are topological stable, spatially compact, and easily driven by electrical currents3,4. However, skyrmions are typically only stable in a limited region of phase space - i.e., at certain temperatures, and with an applied external field. To realize their potential in spintronic technologies, skyrmions must be stabilized in commercially viable conditions: at room temperature, with zero applied field, and in a range of physical geometries. Skyrmions have prototypically been studied in with broken inversion symmetry, such as non-centrosymmetric bulk magnets and These inversion symmetry to the competes collinear interactions like the to stable swirling spin manipulating interfacial DM interactions7, creating tailored skyrmions at room-temperature and with no applied
