The magnetoelectric (ME) effect delineates the connection between magnetism and electricity. It appears in two different forms : the direct effect, where the application of an electric field induces magnetization changes, and the inverse effect, in which a magnetic field leads to alterations in electrical polarization. The focus of this thesis will be the inverse ME effect . It will be studied in multilayer composites, specifically piezoelectric/ magnetostrictive materials, where the interaction between the two layers allows the transfer of deformation-induced magnetostriction to the piezoelectric component, resulting in dielectric polarization. The stack under investigation is consisted by PVDF-TrFe as piezoelectric layer and Ni as magnetostrictive layer.
