Abstract A lattice model is proposed to describe the stripe domain sructure in a magnetic ultrathin film that consists of only a few or tens of monolayers and has a perpendicular anisotropy.The dipolar energies of the perpendicular and in-plane uniform magnetic states and the stripe domain structures in a magnetic ultrathin film are calculated separately using Ewald's lattice summation method. The thickness dependence of the stripe domain structure is investigated, and the stability of the stripe dimain structure is discussed. The results show that for magnetic ultrathin films the stripe dimain structure may have sensitive dependence on their thickness.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
