摘要：

The micromagnetic structure of Bloch lines separating 180 degrees domain-wall sections with differing symmetry in 60 nm {1 0 0} iron films has been calculated. The flux of transverse magnetization in the wall sections was 'S'-shaped, normal to the film plane in the interior and parallel to it near the surfaces. Stable structures were obtained for (i) two 'S' sections with opposite normal flux, (ii) 'S' and 'mirror-S' sections with parallel flux. The energy of the latter is slightly lower than that of the former. (C) 1998 Elsevier Science B.V. All rights reserved.
