Abstract
The effect of the interdot magnetostatic interaction on the magnetization reversal due to the "nucleation" and "annihilation" of magnetic vortices in arrays of ferromagnetic submicron circular dots has been investigated experimentally and theoretically. The magnetostatic interaction plays an important role in magnetization reversal for the arrays with a small interdot distance, leading to decreases in the vortex nucleation and annihilation fields, and an increase in initial susceptibility.
