From Bubble to Skyrmion: Dynamic Transformation Mediated by a Strong Magnetic Tip
arXiv:cond-mat/0305487 · doi:10.1016/j.jmmm.2006.01.113
Abstract
Skyrmions in thin metallic ferromagnetic films are stable due to competition between the RKKY interaction and uniaxial magnetic anisotropy. We mimic the RKKY interaction by the next-nearest-neighbors ferromagnetic and antiferromagnetic exchange interactions. We demonstrate analytically and numerically dissipative transformation of a bubble created by a strong cylindrical magnetic tip into a stable Skyrmion.
