摘要

As a member of 1D nanostructured materials,the ferromagnetic and nonmagnetic multilayer nanowires exhibit tremendous potential applications in many fields due to their unique magnetic and electrical properties.The basic property of multilayer nanowire arrays,such as coercivity,is crucial important for the future application.In order to obtain the coercivity information,besides directly measuring it through experiment,theoretical calculation also provides a useful and fast way to evaluate the multilayer’s coervicity.Fig.1(a)and(b)demonstrate a single multilayer nanowire and nanowire arrays embodied in a matrix,respectively.In this work,by improving Pant’s model,we developed the new model and successfully predicted the relationship between the coercivity changing of Cu/Ni multilayer nanowire arrays and structual parameters.Fig.
