Effect of load resistance on magnetoelectric properties in FeGa/BaTiO3/FeGa laminate composites

Load Resistance Influence of Magnetoelectric Characteristics on NiZnFe2O4+PZT Composites for Magnetoelectric Sensors

“…The maximum output power occurred when the output impedance matched the load impedance as previously mentioned. A similar load resistance influence has been observed in other ME materials [15][16][17]. Thus, the ME output power of this sample can be adjusted by changing R L .…”

“…7 shows the frequency dependence of the ME coefficient for the 0.2NZFO+0.8PZT sample at an ac field Hac=1 Oe, an optimal bias static field Hdc=780 Oe, and various load resistance R L (including the opencircuitcondition). The previous research on the influence of the load resistance was also observed in other ME materials [15][16][17].…”

“…The study on the influences of the load resistance of ME characteristics requires the use of a practical ME sensor. Recently, research groups have focused on the influence of the load resistance R L to enable ME sensor applications, and their research has been performed in other ME materials [15][16][17]. However, the research on the influence of the load resistance on the NiZnFe 2 O 4 +PZT composite has not yet been comprehensively conducted.…”

Performance of magnetoelectric PZT/Ni multiferroic system for energy harvesting application

“…In a recent report, Galizia et FeGa laminate composites and reported a low value of 8 mV Oe −1 as ME coefficient [16]. Moreover, silver epoxy has been used by Wang et al to stack FeGa and BaTiO 3 pallets which results in losses [16]. Laletin et al have also reported that Ni with PZT shows the maximum ME coefficient as compared to other magnetostrictive materials [17].…”

“…Simultaneously, it is important to select a suitable ferromagnetic material having efficient magnetostrictive properties. In a recent report, Galizia et FeGa laminate composites and reported a low value of 8 mV Oe −1 as ME coefficient [16]. Moreover, silver epoxy has been used by Wang et al to stack FeGa and BaTiO 3 pallets which results in losses [16].…”
