摘要翻译：
我们描述了一种新型的磁畴壁，与Bloch或Neel壁相比，它是非局域的，在一定的温度范围内是非单调的。壁面表现为二维铁磁Ising模型的平均场解，受到长程偶极相互作用的影响。我们提供了垂直磁化超薄磁膜条畴相中这种壁面离域的实验证据。与实验结果一致，我们发现条纹宽度随温度的升高而减小，并在居里温度下接近一个有限值，遵循幂律。在二维库仑受挫Ising铁磁体的平均场近似中，可以得到相同的壁面和类似的条带宽度的温度依赖关系。

英文摘要：
  We describe a novel type of magnetic domain wall which, in contrast to Bloch or Neel walls, is non-localized and, in a certain temperature range, non-monotonic. The wall appears as the mean-field solution of the two-dimensional ferromagnetic Ising model frustrated by the long-ranged dipolar interaction. We provide experimental evidence of this wall delocalization in the stripe-domain phase of perpendicularly magnetized ultrathin magnetic films. In agreement with experimental results, we find that the stripe width decreases with increasing temperature and approaches a finite value at the Curie-temperature following a power law. The same kind of wall and a similar temperature dependence of the stripe width is expected in the mean-field approximation of the two-dimensional Coulomb frustrated Ising ferromagnet.
