Abstract

The dependence of the magnetic characteristics of permalloy nanostructures on their sizes has been studied by the micromagnetic simulation method. The critical size of a square-shaped nanoisland for transition into a single-domain state has been estimated. The dependence of the coercive force of the nanoisland on its thickness and area has been studied.
