用磁力显微镜研究了由三角形点和等腰三角形点组成的静磁耦合链阵列的磁畴结构。尽管在点链阵列中存在很强的静磁相互作用，但每个三角形点都具有单一的涡旋结构。发现每个点的手性与孤立三角形点的手性相似。我们还证明了具有所需手性的单涡和双涡结构可以稳定在等腰三角形点上。
We have studied the magnetic domain structures in a magneto-statically-coupled chain array of the triangle dots and an isosceles triangle dot by means of magnetic force microscopy (MFM). Despite the strong magneto-static interaction in the chain array of the dots, each triangle dot takes a single vortex structure. The chirality of each dot is found to behave similarly to that for the isolated triangle dot. We also demonstrated that single-vortex and double-vortex structures with the desired chiralities can be stabilized in an isosceles triangle dot.
