ABSTRACT
A micromagnetic simulation is performed of a device consisting of arrays of square magnetic nanostructures, which is capable not only of basic logic operations but also controlled information transfer in linear, fan-out, and crossover manner by means of magnetic ‘solitons.’ The square elements exhibit shape anisotropy, with easy axes along the diagonals. This enables the solitons to propagate around a bend in an array, or to fan-out into two distinct directions in Y-shaped arrays, in the presence of particular external field sequence and direction. Finally, independent soliton crossover at the intersection of two arrays is also demonstrated, which completes the device's logical functionality.
