文摘

Study of Ni nanowire (NW) arrays with uniform and non-uniform length distributions. First-order-reversal curve (FORC) analysis and micromagnetic simulations are used. Strongly- from weakly-interactions in a magnetic array are distinguished using FORC. Distinct magnetization reversal modes for interacting and isolated NWs are obtained.
