Abstract
The domain structure and the switching field of Co50 Ni50 /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.
