Abstract
The effect of interdot magnetostatic coupling on magnetization reversal due to nucleation, displacement and annihilation of magnetic vortices in arrays of circular permalloy dots has been studied experimentally. The magnetostatic coupling leads to decrease in both the vortex nucleation and annihilation fields, and an increase in susceptibility. The experimental data is interpreted using micromagnetic numerical calculations.
