| Abstract: | Dependence of magnetoelectric modulus and phasic difference on the bias magnetic field was studied in a magnetoelectric Pb(Zr, Ti)O3/Terfenol-D laminate composite. The shifts of both magnetoelectric resonant peak and phasic bounce under the bias magnetic field lead to a nonlinear relationship between them. The acoustic velocity of Terfenol-D has a nonlinear dependence on magnetic field, resulting in a similar relationship between the acoustic velocity of the composite and magnetic field. As a result, the magnetoelectric modulus and phase around the resonance frequency exhibit very sensitive dependences on the bias magnetic field. |
