Exploring the unusual linear magnetolectric at EMR resonance in PZT/NFO composites
Source abstract
Abstract
Magnetoelectric materials are widely studied due to their characteristic of having two different coupled ferroic orders. The magnetoelectric coupling depends on the excitation frequency of the AC magnetic field and reaches the highest values at the electromechanical resonance frequency of the material. In this sense, this work studied the magnetoelectric response of the PZT/NFO magnetoelectric composite at EMR. Measurements of the ME coefficient were performed as a function of magnetic field and with frequencies around the EMR frequency. These measurements showed a superimposed linear response to the typical stress behavior caused by ferrite magnetostriction. An increase in the resonance frequency was also observed with the applied magnetic field for the electrical impedance analyses. These measurements’ behavior was related to the electric dipole moment interaction between the ferroelectric and ferrimagnetic phases.
