Analysis of magnetic interaction in Ni nanowire array grown using electrodeposition process

Simulation and comparison of magnetic properties were performed on three types of Ni nanowire arrays grown by electrodeposition using commercial nano channel alumina (NCA) templates with nominal pore sizes of 200, 100 and 20 nm. Experimental observations on the structural behaviour of the nanowires grown inside the pores of NCA templates show that the magnetic interaction depends on the effective pore diameter and the interpore distance. A numerical simulation model based on micromagnetic calculations using object-oriented micromagnetic computing framework (OOMMF) has been developed and reported experimental results on coercivity of Ni nanowires generally agreed with the simulated ones.
