Theory of magnetic force driven magnetoelectric effect in piezo-bimorph/ferrite cantilever composite
A theoretical model is proposed for the frequency response of the magnetic force driven (MFD) magnetoelectric (ME) effect in a piezo-bimorph/ferrite cantilever based on the elastodynamics method, which agrees well with the experimental results for Pb(Zr, Ti)O3-bimorph/Mn–Zn-ferrite cantilever compos...

| Summary: | A theoretical model is proposed for the frequency response of the magnetic force driven (MFD) magnetoelectric (ME) effect in a piezo-bimorph/ferrite cantilever based on the elastodynamics method, which agrees well with the experimental results for Pb(Zr, Ti)O3-bimorph/Mn–Zn-ferrite cantilever composites. Based on the theoretical model, the dependences of the resonant ME voltage coefficient on geometrical and material parameters of the piezo-bimorph/ferrite cantilever composite are numerically calculated. The results show that an optimum resonant ME effect can be achieved by adjusting the structural and material parameters in the piezo-bimorph/ferrite cantilever composite. This research lays a theoretical basis for understanding the resonant ME effect in the piezo-bimorph/ferrite composite and optimal design of the MFD-ME device based on this configuration. |
