Abstract
The phenomenon of transformation of the spectrum of magnetic noise in a Metglas/PZT/Metglas magnetoelectric (ME) planar composite structure has been experimentally discovered and investigated. It is established that a narrowband noise with central frequency fN leads to the linear generation of electric noise voltage at the noise frequency and the nonlinear generation of noise voltage in the vicinity of zero frequency and in the region of 2fN. The experiment is well explained by the theory of magnetic-field mixing in ME composites with nonlinear field dependence of the ferromagnetic-layer magnetostriction.
