Abstract

In this work, 1-D nickel nanowires with different diameters were synthesized. Magnetic properties of the products were investigated by using first-order reversal curves (FORC) experimental testing, and magnetization reversal processes were theoretically simulated based on the Object Oriented Micro Magnetic Framework (OOMMF) software. The experimental results show different shapes of FORC patterns, indicating the influence of the diameter on the magnetization switching processes of the nanowires. Micromagnetic simulations were carried out on a model of two parallel cylindrical nanowire systems, and the simulation results indicated that both the shape anisotropy and magnetostatic interactions played important roles in identifying the magnetization reversal processes. Furthermore, by means of micromagnetic slicing, the real time distribution status of magnetic moments in the two parallel nickel nanowires had been illustrated visually, which showed that the magnetization reversal process in the two parallel nanowires were different especially in the x and y directions, although of the same objective condition.
