Abstract

In this study, we demonstrate experimentally using longitudinal and diffracted magneto-optical Kerr effect measurements and confirmed by theoretical modeling that localized magnetic field sources can be used to actively induce and finely control the magnetization states and reversal paths of nanomagnets beyond what achievable via lateral confinement and anisotropy engineering, and that such localized field sources can be easily facilitated within the appropriate array structure.
