Item Micromagnetic simulations of the domain structure and the magnetization reversal of Co50Ni50/Pt multilayer dots(Elsevier, 2002-01) Nair, Sindhu S.The domain structure and the switching field of Co50Ni50/Pt multilayer dots, prepared by laser interference lithography, were micromagnetically simulated. The simulations were carried out with a three-dimensional simulation package, optimized for large-scale problems. The single-domain state is the lowest energy state for dots with a diameter below 75 nm. The switching field was computed by using suitable minimization techniques, and was used to analyze the effect of size, dot shape and edge defects.
