Magnetic structures in dipolar coupled multilayers — •Oleg Petracic, Subhankar Bedanta, and Wolfgang Kleemann — Angewandte Physik, Universität Duisburg-Essen, 47048 Duisburg, Germany
Metal-insulator multilayers can show various kinds of magnetization structures due to the competition of the usual magnetostatic and the so-called Néel inter-layer coupling. The second one becomes significant, when the roughness of the ferromagnetic films is large. We performed micromagnetic simulations motivated by recent experimental studies on the multilayers [Co80Fe20/Al2O3]n. Varying different parameters, like roughness and interlayer distance various regimes of layer ordering can be observed.
