摘要

研究表明，由于不均匀磁场的轨道效应，超导珍珠涡旋的杂散磁场可以与高阶磁天线形成束缚态。通过类比拓扑电荷 |Q| = 1 的天空态的最新结果 [E. S. Andriyakhina, J. M., M., M., M., M., M., M., M., M.S. Andriyakhina, S. Apostoloff, and I. S. Burmistrov, JETP Lett.116，825 (2022)]，这种束缚态中的高阶磁天幕中心可以相对于超导漩涡中心移动。研究表明，作用在拓扑电荷 |Q| = 2 的最简单高阶磁性天元上的思索力往往会形成非同轴束缚态。

Bound States of High-Order Magnetic Skyrmions and a Superconducting Pearl Vortex

It has been shown that stray fields of a superconducting Pearl vortex can form bound states with high-order magnetic skyrmions due to orbital effects of an inhomogeneous magnetic field. By analogy with recent results for skyrmions with the topological charge |Q| = 1 [E. S. Andriyakhina, S. Apostoloff, and I. S. Burmistrov, JETP Lett. 116, 825 (2022)], the centers of high-order magnetic skyrmions in such bound states can be shifted with respect to the center of the superconducting vortex. It has been shown that ponderomotive forces acting on the simplest high-order magnetic skyrmions with the topological charge |Q| = 2 tend to form noncoaxial bound states.
