Abstract

Microwave properties of magnetic metallic nanostructures with giant magnetoresistive effect are studied. Two main physical reasons cause microwave variations, namely the microwave analog of giant magnetoresistive effect and ferromagnetic resonance. A comparison is outlined with the DC magnetoresistive effect. Methods of microwave magnetoresistive effect measurement are presented. The experiments in the "current perpendicular-to-plane" geometry are specially considered, and the experiments carried out in the millimeter waveband are presented. The peculiarities of the joint observation of ferromagnetic resonance and microwave magnetoresistive effect are specified. Application of the metallic magnetic nanostructures in microwave electronics is discussed.
