Abstract
Various magnetic wire and box arrays were prepared by high-resolution electron-beam lithography and lift-off techniques. Both the coercive force and demagnetizing field for the Ni80Fe20 arrays with a constant wire width decreased with the inter-wire distance. When a static field was applied normal to the NiA80Fe20 stripes and parallel to the array plane, multiple microwave absorption was observed at fields higher than the uniform precessional mode. These results indicate the presence of long-range magnetic interaction. Magnetoresistance (MR) characteristics of the wire arrays comprising three types of giant MR multilayers are also reported here.
