“…The higher value of this parameter can be achieved in magnetoelectric material at room temperature, and the wider range of its potential applications can be expected. The most frequently mentioned prototypes of magnetoelectric devices which were developed so far are magnetic field sensors [9–11] and energy harvesting devices [12–14]. Among the new proposals for the use of magnetoelectric coupling phenomenon, the most spectacular and forward-looking ideas seem to be new-generation memories [15–17], spintronic devices (e.g., spin valves, magnetic tunnel junctions) [18–20], microwave, millimeter-wave devices and miniature antennas [14], and wireless medical tools (e.g., for endoscopy and brain imaging) [14].…”

Solid-state sintering method was used to prepare ceramic materials based on bismuth ferrite, i.e., (BiFeO3)1 − x–(BaTiO3)x and Bi1 − xNdxFeO3 solid solutions and the Aurivillius Bi5Ti3FeO15 compound. The structure of the materials was examined using X-ray diffraction, and the Rietveld method was applied to phase analysis and structure refinement. Magnetoelectric coupling was registered in all the materials using dynamic lock-in technique. The highest value of magnetoelectric coupling coefficient αME was obtained for the Bi5Ti3FeO15 compound (αME ~ 10 mVcm−1 Oe−1). In the case of (BiFeO3)1 − x–(BaTiO3)x and Bi1 − xNdxFeO3 solid solutions, the maximum αME is of the order of 1 and 2.7 mVcm−1 Oe−1, respectively. The magnitude of magnetoelectric coupling is accompanied with structural transformation in the studied solid solutions. The relatively high magnetoelectric effect in the Aurivillius Bi5Ti3FeO15 compound is surprising, especially since the material is paramagnetic at room temperature. When the materials were subjected to a preliminary electrical poling, the magnitude of the magnetoelectric coupling increased 2–3 times.

“…Since these magnetic sensors can detect only changes in a magnetic field, a sensing scheme using a DC bias magnetic field might be adopted. Typical magnetostrictive/piezoelectric stacked-layer magnetic sensors use PZT as a piezoelectric material, sandwiched with magnetostrictive materials such as Terfenol-D (Tb x Dy 1-x Fe 2 ) [9,10], FeCoBSi [11], or FeGa [12]. In our previous study in which basic and temperature characteristics of FeGa thin plates [13] were evaluated, the measured results were considerably influenced by the temperature dependence of the epoxy adhesive used to bond the magnetostrictive and piezoelectric plates.…”

FePd/PZT/FePd and FePd/PZT stacked-layer magnetic sensors were studied. A magnetic field was applied to the longitudinal direction of the sensor to cause longitudinal stress magnetostrictively, producing a piezoelectric output voltage in the PZT layer. The prototype sensors were 15 mm long and 6 mm wide and the thicknesses of the FePd layer and PZT layer were 10 and 330 µm, respectively. The theoretical sensitivities of the FePd/PZT/FePd sensor and the FePd/PZT sensor using a simple cantilever model were calculated to be 0.29 and 0.15 mV/A/m, respectively. The measured sensitivities agreed reasonably well with the calculated ones.

“…However, a much stronger extrinsic effect can be obtained in multi-phase composites using magnetostrictive and piezoelectric materials as active constituent phases to impart a stress-mediated product property between magnetostrictive and piezoelectric phases within the composites [3][4][5]. In order to enable potential applications, ME composites have been optimized in numerous aspects including the individual magnetostrictive phase [6][7][8][9][10], the piezoelectric phase [5,8,9], the mode of coupling, and the manner in which magnetic (H) and electric (E) fields are applied [11][12][13].…”
