摘要: We used micromagnetic simulations to investigate the spatial distributions of effective magnetic fields induced by spin chirality in crossed nanowires with three characteristic structures: a radiated-shape, an antivortex, and uniform-like states. Our results indicate that, unlike anomalous Hall effect, topological effect (which is related chirality) depends on both polarity vorticity. Therefore, measuring can detect vorticity simultaneously nanowires. This approach may be suitable for use as elemental technique quest next-generation multi-value memory.
