| Abstract: | Magnetization-induced third harmonic (TH) generation was observed in magnetic nanostructures—nanogranular CoxAg1? x films—possessing giant magnetoresistance (GMR). The magnetization-induced contribution to the TH intensity was studied as a function of the concentration of a magnetic component (cobalt) in the films. Magnetic contrast of the TH intensity was found to correlate with the GMR coefficient: both parameters simultaneously reach extremum in the range of cobalt concentrations x～0.3–0.35. |
