论文摘要
在本文中，我们研究了由于流浪场而产生的超导珍珠涡流的手性铁磁膜中Néel型Skyrmion的排斥。考虑到涡流磁场对天际的影响非扰动，我们发现它们之间的排斥力随着涡旋磁场的无量纲强度的增加而被抑制。随着涡流磁场的增加以及Néel-Type Skyrmion和Pearl Vortex中心之间的平衡距离的降低，自由能的复杂演变和降低。
In this paper we study repulsion of a Néel-type skyrmion in a chiral ferromagnetic film from a superconducting Pearl vortex due to the stray fields. Taking into account an effect of the vortex magnetic field on the skyrmion non-perturbatively, we find that the repulsion between them is suppressed with increase of the dimensionless strength of the vortex magnetic field. This manifests itself in complicated evolution of the free energy with increase of the vortex magnetic field and reduction of the equilibrium distance between the centers of Néel-type skyrmion and Pearl vortex.
