Abstract

This work explores the possibility of using dynamic magnetization phenomena in nanostructured magnetic materials for information processing. We investigate two physical systems: (1) regular arrays of coupled nanoscale magnets and (2) a magnetic film, which interacts with stray field of nanomagnets. We numerically solve the differential equations that describe the magnetization dynamics of this system and explore propagation of disturbances and pattern formation phenomena in the array. We argue that magnetic systems possess all the necessary characteristics to build a large-scale cellular signal processing circuit.
