摘要: We have studied the magnetic domain structure in Permalloy rectangles that reveal flux-closure configurations. Arrays with varying spacing between are investigated by scanning electron microscopy polarization analysis as well micromagnetic simulation. In contrast to general expectation, Landau state show significant coupling and form a pattern of common chirality. The is due stray field originates from small changes magnetization alignment, which sensitive exact shape separation rectangles.
