Temperature dependence of the magnetoelectric (ME) coefficient was studied for FeBSiC/Pb(Zr, Ti)O3(PZT)/FeBSiC laminates over temperature range of - 35 ∼ 85 °C. The variation in ME coefficient as a function of temperature was found to be significantly dependent on the volume fraction of FeBSiC layers and the lateral dimension of the laminate composites. Our results show that minimum number of FeBSiC layer with smaller lateral dimension can provide more stable ME coefficient in wide temperature range, due to the competition of the effects of temperature influenced piezoelectricity, magnetostriction, and mechanical properties of the constituents and the interfacial bonding layer. This finding indicate that it is beneficial to promote miniaturization of the ME composite based devices in view of temperature stability.
