How to Observe Dipolar Interaction of Coupled Nanodot Patterned Structure in the Inverse Space

Two dimensional Permalloy circular –ellipsoidal nanodots array were investigated by using object orientedmicromagnetic framework (OOMMF) code. The effect of shape anisotropy and dipolar coupling were studied bysimulating hysteresis loop of magnetic members. The dipolar coupling effect on vortex propagation as well as reflectedand diffracted magnetic loop from both ellipsoidal and circular islands were also investigated
