我们数值计算和实验研究了矩形坡莫合金反点晶格中由反点缺失组成的单个缺陷对自旋组态的影响。这种晶格缺陷的引入导致在饱和磁场衰减后复杂畴结构的成核。微磁模拟产生四个典型的域配置周围的缺陷具有不同的能量密度。四个自旋配置的存在证实了磁力显微镜上的反点晶格含有个别缺陷。(C)2013年美国物理学会。[http：//dx.doi.org/10.1063/1.4795147]
We numerically and experimentally investigate the influence of single defects consisting of a missing antidot on the spin configurations in rectangular permalloy antidot lattices. The introduction of such lattice defects leads to the nucleation of complex domain structures after the decay of a saturating magnetic field. Micromagnetic simulations yield four typical domain configurations around the defect having distinct energy densities. The existence of the four spin configurations is confirmed by magnetic force microscopy on antidot lattices containing individual defects. (C) 2013 American Institute of Physics.
