“…Efforts have focused on: (a) different categories of sensor construction [24,[74][75][76], geometry and other features [77][78][79][80]; (b) packaging of the sensor units; (c) improvements in fabrication techniques [81]; (d) signal processing conditions [82,83]; and (e) gradiometric configurations to reduce environmental noise sources [84]. The multi-push-pull configurations, multilayer configuration, and bimorphs, all of which exhibit an improved ME voltage coefficient, have demonstrated considerable potential for sensing low-frequency magnetic field variations.…”

Multiferroic magnetoelectric (ME) composites are attractive materials for various electrically and magnetically cross-coupled devices. Many studies have been conducted on fundamental understanding, fabrication processes, and applications of ME composite material systems in the last four decades which has brought the technology closer to realization in practical devices. In this article, we present a review of ME composite materials and some notable potential applications based upon their properties. A brief summary is presented on the parameters that influence the performance of ME composites, their coupling structures, fabrications processes, characterization techniques, and perspectives on direct (magnetic to electric) and converse (electric to magnetic) ME devices. Overall, the research on ME composite systems has brought us closer to their deployment.

“…Details of the measurement can be found in Ref. 6. In Figure 2(b), one can clearly see with increasing temperature between À50 T 50 C that the ME sensor unit gain factor a me increased slightly, which can be attributed to changes in the piezoelectric charge coefficient (d 33 ).…”

“…3,4 To date, ME laminated composites of magnetostrictive Metglas foils and piezoelectric Pb(Zr,Ti)O 3 or PZT have been widely investigated in various operational modes and optimized for use in magnetic field detection applications. [5][6][7] Highly sensitive, room temperature, passive magnetic field sensors have been developed based on ME laminates. Such magnetic sensors have been shown to have noise floors on the order of pT/HHz for Metglas/PZT foil laminates.…”

“…The low-frequency MEVC values in Fig.6 for quartz-P bilayers and trilayers are orders of magnitude higher than reported values for bulk ferritepiezoelectric composites, for bilayers and trilayers of ferrite-PZT and lanthanum manganite-PZT [1][2][3]. The maximum MEVC at 20 Hz in Fig.6 compares favorably with MEVC of 3 -52 V/cm Oe at 1 kHz for Metglas composites with PZT fibers and single crystal PMN-PT or PZN-PT [19,20].…”

Magnetoelectric interactions in layered composites of piezoelectric quartz and magnetostrictive alloys

Mechanical strain mediated magnetoelectric effects are studied in bilayers and trilayers of piezoelectric quartz and magnetostrictive permendur (P), an alloy of Fe-Co-V. It is shown that the magneto-electric voltage coefficient (MEVC), proportional to the ratio of the piezoelectric coupling coefficient to the permittivity, is higher in quart-based composites than for traditional ferroelectrics based ME composites. In bilayers of X-cut single crystal quartz and permendur, the MEVC varies from 1.5 V/cm Oe at 20 Hz to ~ 185 V/cm Oe at bending resonance or electromechanical resonance corresponding to longitudinal acoustic modes. In symmetric X-cut quartz-P trilayers, the MEVC ~ 4.8 V/cm Oe at 20 Hz and ~ 175 V/cm Oe at longitudinal acoustic resonance. Trilayers of Y-cut quartz and permendur show ME coupling under a shear strain with an MEVC that is an order of magnitude smaller than for longitudinal strain in samples with X-cut quartz. A model for low-frequency and resonance ME effects which allows for explicit expressions of MEVC and resonance frequencies is provided and calculated MEVC are in general 2 agreement with measured values. Magneto-electric composites with quartz have the desired characteristics such as the absence of ferroelectric hysteresis and pyroelectric losses and could potentially replace ferroelectrics in composite-based magnetic sensors, transducers and high frequency devices.
