Magnetization Reversal of Nickel Three-Dimensional Antidot Arrays

Three-dimensional antidot arrays (3DAAs) have attracted considerable attention due to potential applications in photonic materials, sensitive sensors and high-capacity electrode materials. The periodic structure and high surface-to-volume ratio of magnetic 3DAAs provide an ideal system for studying the effect of the dimensionality and morphology on magnetic properties. Most of the work has focused on the dependence of coercivity on the dimensions in magnetic 3DAAs so far. In this work, we report our study of magnetization reversal in Ni 3DAAs by the first-order reversal curve (FORC) method [1] and micromagnetic simulations.
