摘要: We have performed an experimental study into magnetostatic coupling between Permalloy nanomagnets arranged in linear chains. By engineering the anisotropy of each nanomagnet, can be forced to couple antiferromagnetic arrangement. Using method, we show that is perfect for first four chain, but thereafter phase defects arise. Differences information transmission capability ferromagnetic and are discussed.
