Abstract

This chapter focuses on the dynamic properties of nanowires. It shows how the properties of nanowires change from a single nanowire (or a large ensemble of noninteracting nanowires) to a strongly interacting nanowire system. The dominating role of the long-range magnetostatic dipolar interactions is demonstrated in establishing a configurational reorientation transition. The interaction of magnetic nanowires with electromagnetic waves (EMWs) leads to a specific spin-wave excitation spectrum due to its size and shape sensitivity. ...
