Schaefer和Hubert[Phys]报道了铁磁磁畴壁的磁光图像的反常对称性。地位Solidi A 118,271(1990)]，并用与磁化梯度成正比的光幅来解释。我们给出了在经典微磁学规则所暗示的附加条件下支持这种比例的解析和数值计算，并解决了Banno[Phys]提出的一些异议。A 77,033818(2008年)修订版]反对这种相称性。
An anomalous symmetry of magneto-optical images of ferromagnetic domain walls was reported by Schaefer and Hubert [Phys. Status Solidi A 118, 271 (1990)] and interpreted in terms of light amplitudes proportional to the magnetization gradient. We present analytic and numerical calculations supporting such proportionality under additional conditions implied by classical rules of micromagnetics and address some objections presented by Banno [Phys. Rev. A 77, 033818 (2008)] against such proportionality.
