Micromagnetic simulations of magnetostatically coupled nickel nanowires

Using a micro magnetic algorithm based on the finite element combined with the boundary method, hysteresis loops and magnetization states of magneto statically coupled Nickel nanowires can be simulated without making use of simplifying assumptions. The most pronounced influence of the magneto static coupling on the shape of the hysteresis loops of an ensemble of wires is the reduction of the coercive field with an increasing number of interacting wires and only if the magneto static interaction of several wires is considered, the coercive field of the array approaches the experimental value well.anl
