摘要
In the present work, results about the effects of the length distribution in hexagonal arrays of nine nickel na- nowires were obtained by micromagnetic simulation. Arrangements with average nanowires length of 500 nm and different length dispersion (sigma = 0, 15, 62.49, 92.47 nm) were simulated. The effects of the length dis- tribution on magnetization curves are not relevant and the angular dependence of the remanence and coercivity does not present significant variations. Despite that, for the reversal process, there are variations as the sigma value increases. Moment configuration maps showed important information for the reversion, suggesting that hys- teresis curves are not sufficient in arrays of nine nickel nanowires.
