摘要: Square lattice arrays of thin microelements Fe are investigated by magnetic transmission x-ray microscopy. The influence dipole interaction is analyzed varying the interelement distance. For comparison isolated elements prepared on same sample. magnetostatic field caused leads to a substantial stabilization in center array comparable magnetization process previously found numerical solution Landau-Lifshitz equation for dot arrays. Micromagnetic simulations show that high strengths dipolar collinear with external while low-field regime strayfields have significant perpendicular components leading complex reversal mechanism.
