摘要：

Optical coatings applied to one-half of thin film magnetic rings allow real-time readout of the chirality of the vortex state of micro- and nanomagnetic structures by breaking the symmetry of the optical signal. We use this technique to demonstrate data storage, operation of a NOT gate that uses exchange interactions between slightly overlapping rings, and to investigate the use of chains of rings as connecting wires for linking gates.
