Abstract

The microwave properties of magnetic metallic nanostructures with a giant magnetoresistive effect are studied in this work. The microwave refractive index is calculated; it is shown that its changes have two physical causes: the high-frequency giant magnetoresistive effect and the ferromagnetic resonance.
