Abstract
The effects of an electric field on the magneto-dynamics of a FeGaB/PZN-PT (lead zinc niobate-lead titanate) multiferroic heterostructure were investigated. It was found that with the increase of electric field applied on the PZN-PT layer, the magnetoelectric coupling is increased, and the magnetization of the FeGaB film changes gradually from an unpinned to a pinned boundary condition at the FeGaB/PZN-PT interface. This change leads to the observation of the first-order standing spin wave mode and the varied resonance intensity ratio between the standing mode and the uniform mode from 1 to 5 in the FMR spectra. The E-field induced surface anisotropy change confirms the strain mediated magnetoelectric mechanism through the interface between multiferroic heterostructures.
