LAROZE, D.; VARGAS, P.; ALTBIR, D. and VAZQUEZ, M.. Box model for hysteresis loops of arrays of Ni nanowires. Braz. J. Phys. [online]. 2006, vol.36, n.3b, pp. 908-909. ISSN 0103-9733. http://dx.doi.org/10.1590/S0103-97332006000600029.
In the present work, by means of a phenomenological model, we simulate the hysteresis loop of an hexagonal array of Ni nanowires. Our model is based on the assumption that the hysteresis loop of a single wire is a rectangular box with a particular value of the coercive field, and the effect of the array is to generate a distribution of the coercive fields. Our results are in good agreement with experimental data.
