要旨:
We report a magnetic X-ray microscopy study of the pattern formation of circulation in arrays
of magnetic vortices ordered in a hexagonal and a honeycomb lattice. In the honeycomb lattice,
we observe at remanence an ordered phase of alternating circulations, whereas in the hexagonal lat-
tice, small regions of alternating lines form. A variation in the edge-to-edge distance shows that the
size of those regions scales with the magnetostatic interaction. Micromagnetic simulations reveal
that the patterns result from the formation of flux closure states during the nucleation process.
