论文摘要
中心对称结构的挫败感产生的天际含量具有额外的内部自由度:涡度和螺旋性,从而产生了独特的特性和潜在功能,这不是由dzyaloshinskii-Moriya相互作用在非中性质合结构中所产生的天际。目前的工作表明,磁性驱动的电动极化为Skyrmions携带提供了直接调节螺旋性的手柄。特别是对于面内磁化的天空,可以连续旋转螺旋,并通过在天空和反扰动物中施加外部电场来精确挑选。平面单轴各向异性对这种操作有益。
The skyrmions generated by frustration in centrosymmetric structures host extra internal degrees of freedom: vorticity and helicity, resulting in distinctive properties and potential functionality, which are not shared by the skyrmions stemming from the Dzyaloshinskii-Moriya interaction in noncentrosymmetric structures. The present work indicates that the magnetism-driven electric polarization carried by skyrmions provides a direct handle for tuning helicity. Especially for the in-plane magnetized skyrmions, the helicity can be continuously rotated and exactly picked by applying an external electric field for both skyrmions and antiskyrmions. The in-plane uniaxial anisotropy is beneficial to this manipulation.
