论文摘要
我们介绍了手性孤子晶格的高度非线性状态的非线性AC磁反应理论。垂直于手性轴的直流磁场的增加导致了相位的交叉，当时几乎隔离的$2π$ -kinks被巨大的铁磁域分配。假设每个扭结都从其他方面独立于外部AC场做出反应，我们证明了这种扭结的内部变形会产生非线性响应。
We present the theory of nonlinear ac magnetic response for the highly nonlinear regime of the chiral soliton lattice. Increasing of the dc magnetic field perpendicularly to the chiral axis results in crossover inside the phase, when nearly isolated $2π$-kinks are partitioned by vast ferromagnetic domains. Assuming that each of the kink reacts independently from the other ones to the external ac field, we demonstrate that internal deformations of such a kink give rise to the nonlinear response.
