Controlling the Characteristics of the Magnetoelectric Effect in Composite Resonators through External Actions

详细

The possibility of controlling the characteristics of the low-frequency resonant magnetoelectric effect in composite structures using external effects is demonstrated. These composite structures contain ganged ferromagnetic and piezoelectric layers. The magnitude of the magnetoelectric effect in planar structures with layers of nickel and lead zirconate titanate changes by tens of percent, and the frequency of acoustic resonance is altered to ten percent under the action of a constant magnetic field or a constant electric field when the temperature changes or mechanical stresses are created in the structure.
