Abstract Magnetic skyrmion bubbles are swirling magnetic textures with novel characteristics suitable for future applications in spintronic devices. Here, high-density nanometric bubbles are obtained by adding C element in biskyrmion-host MnNiGa materials. Furthermore, the diversified topological spin configurations of nanometric bubbles are manipulated by combining electric current with perpendicular magnetic fields. Different magnetic bubble states including the homogeneous skyrmion bubble state are achieved via electromagnetic manipulation. Via analysing the different magnetic textures obtained via electromagnetic manipulation, we infer that the topological spin configurations of magnetic bubbles are closely related to the relative intensity of external fields applied as magnetic bubbles nucleate.

C-间隙MnNiGa合金中的Skyrmion气泡状态及其磁自旋构型操纵

摘要 磁性斯格明子气泡是具有新颖特性的旋转磁性结构，适用于未来在自旋电子器件中的应用。在这里，高密度纳米气泡是通过在 biskyrmion-host MnNiGa 材料中添加 C 元素获得的。此外，通过将电流与垂直磁场相结合，可以操纵纳米气泡的多样化拓扑自旋配置。通过电磁操纵实现不同的磁气泡状态，包括均匀的斯格明气泡状态。通过分析通过电磁操作获得的不同磁性纹理，我们推断磁泡的拓扑自旋配置与磁泡成核时施加的外部场的相对强度密切相关。
