Abstract

Studies of the interaction of electromagnetic microwaves with [Co88Fe12/Cu]n nanostructures, in which the giant magnetoresistive effect (GMR) is observed, have been carried out. The GMR effect was found to contribute to changes in the microwave complex refraction coefficient, including the refractive index.
