Abstract
The effects of inhomogeneities of the drive field Hz and of the in-plane anisotropy on the generation of vertical Bloch line pairs in the stripe domain wall were investigated numerically. It was found that the inhomogeneity of Hz does not cause the generation of vertical. Bloch line pairs in the linear range of wall motion (i.e. Hz<Hzcrit). In the case of the inhomogeneity of the in-plane anisotropy, however, the generation of vertical Bloch lines appears also for Hz<Hzcrit, provided that such an inhomogeneity is sufficiently large.
