Specifically, the composites\u2019 impedance and capacitance are found to vary with dc magnetic field Hdc, which results from the varied effective dielectric permittivity of the FeGa\/PZT composite with Hdc due to the delta E effect, magnetostrictive effect of FeGa and mechanism responsible for ME coupling between the FeGa and PZT layers. Furthermore, the FeGa\/PZT bilayered composite exhibits both bending and longitudinal vibration modes due to the asymmetrical stress distributions. The maximum \u0394Z\/Z of the FeGa\/PZT composite is about 215% at the antiresonance frequency fa = 28.78 kHz of the bending-mode, which is 2.53 times as high as that at the antiresonance frequency fa = 107.9 kHz of the longitudinal mode, while the maximum \u0394C\/C of the FeGa\/PZT composite is about 406% at the resonance frequency fr = 28.5 kHz of the bending mode, which is 3.5 times as high as that at the antiresonance frequency fa = 106.6 kHz of the longitudinal mode. This study plays a guiding role for the design and corresponding application of magnetic sensors, magnetic-field-tuned electronic devices and multiple frequency ultrasonic transducers.<\/jats:p>","DOI":"10.3390\/s22239283","type":"journal-article","created":{"date-parts":[[2022,11,29]],"date-time":"2022-11-29T02:53:29Z","timestamp":1669690409000},"page":"9283","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Magnetically Tuned Impedance and Capacitance for FeGa\/PZT Bilayer Composite under Bending and Longitudinal Vibration Modes"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0192-8682","authenticated-orcid":false,"given":"Lei","family":"Chen","sequence":"first","affiliation":[{"name":"Key Lab. of Computer Vision and Intelligent Information System, Chongqing University of Arts and Sciences, Chongqing 402160, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fujian","family":"Qin","sequence":"additional","affiliation":[{"name":"Key Lab. of Computer Vision and Intelligent Information System, Chongqing University of Arts and Sciences, Chongqing 402160, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongjie","family":"Wan","sequence":"additional","affiliation":[{"name":"Key Lab. of Computer Vision and Intelligent Information System, Chongqing University of Arts and Sciences, Chongqing 402160, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"ref_1","unstructured":"Landau, L.D., and Lifshitz, E.M.
