Abstract

Summary form only given. Recently, highly ordered nanowires were fabricated using electrodeposition in aluminium templates. The magnetic properties of Ni nanowires can be explained by the shape anisotropy and the magnetostatic interactions, whereas in Co nanowires the crystalline anisotropy of the grains strongly influence the hysteresis properties. In this paper the authors simulate the switching process of granular Co nanowires using the finite element method.
