Height-related magnetoelectric performance of PZT/Ni layered composites

Abstract

The effect of height on performance of the PZT/Ni cylindrical bilayered magnetoelectric (ME) composites was studied in situ in this paper. Multiple resonant peaks appear between 1 and 300 kHz frequency for cylinders of different heights. The first resonance frequency does not change with the cylinder height decreasing, but the second and the third resonant frequencies increase. The first three resonant modes are attributed to the cylinder radial, first-order height resonance, and second-order height resonance, respectively. The appropriate size and resonance frequency were chosen to obtain the highest ME voltage coefficient when designing cylindrical bilayered magnetoelectric devices. This article provides reference to design cylindrical magnetoelectric devices.

Epoxy-free fabrication techniques for layered/2-2 magnetoelectric composite: a review

“…The authors also employed the expressions derived in the literature to explain this behavior which included, the dependence of basic acoustic resonant frequency on the effective Young's modulus, density and structural parameters of the composite. In addition to studies on geometry effects in electrodeposited layered rectangular structures, the effect of height on ME response of cylindrical composite was reported in [106]. A comparative study of the response of various composites in the form of trilayered plate, bilayered plate, and trilayered cylindrical ME structures prepared by electrodeposition technique was conducted in [107], wherein cylindrical composites showed better ME output voltages as compared to plate-based structures for the same thickness ratio of the magnetostrictive and piezoelectric layers.…”
