Giant magnetoelectric effect (under a dc magnetic bias of 2Oe) in laminate composites of FeBSiC alloy ribbons and Pb(Zn1∕3,Nb2∕3)O3–7%PbTiO3 fibers

Abstract

Giant magnetoelectric (ME) voltage and charge coefficients have been found in long-type composites of high-permeability magnetostrictive FeBSiC alloy ribbons laminated together with piezoelectric Pb(Zn1∕3,Nb2∕3)O3–7%PbTiO3 single crystal fibers. The maximum ME voltage and charge coefficients at low frequencies were 10.5V∕cmOe and 1nC∕Oe under a notably low dc magnetic bias of 2Oe; at resonance, these coefficients were dramatically increased to 400V∕cmOe and 42nC∕Oe, respectively. These values are much higher, and the required dc magnetic bias much lower, than those of previously reported Terfenol-D based ME laminates.

Equivalent circuit method for static and dynamic analysis of magnetoelectric laminated composites

“…ceramic-ceramic particle composites of two phases, and Terfenol-D/piezoelectric ceramic particles/polymer three phases) and 2-2 (magnetostrictive/piezoelectric) laminates [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] . These studies confirmed the existence of ME effects in single phase materials or multi-phase composites; and amongst them, giant ME coupling has been found in magnetostrictive/piezoelectric two-phase 2-2 laminate composites, and in recent 2-1 laminates [33,34] .…”

Giant electric-field-induced magnetization in a magnetoelectric composite at high frequency

“…Thus, researchers commonly select large samples for their low electromechanical resonance frequency. 5,[7][8][9][10] This is unfavorable to miniaturize devices. Whereas, dynamic electric field with high frequency is easily applied on the sample for Z c =1/ C p during EIM measurement, where C p is the capacitance of the sample.…”

“…14 On the other hand, the MIE measurement commonly requires Helmholtz coils to generate a dynamic magnetic field. [8][9][10] The impedance of the Helmholtz coils is Z L = L s , where L s is the inductance of the coils, resulting in a difficulty to obtain high-frequency magnetic field. Thus, researchers commonly select large samples for their low electromechanical resonance frequency.…”

A flexible, high-performance magnetoelectric heterostructure of (001) oriented Pb(Zr0.52Ti0.48)O3film grown on Ni foil

“…The high piezoelectric response and the low dielectric constant, due to the strong texturing of the PZT grains and their domain state, presumably contributed to the larger ME output, since α ME ∝ g ij (=d ij /ε ij ), where ε ij is dielectric permittivity and g ij and d ij are piezoelectric voltage and charge coefficients, respectively. 31,32 The low permittivity achieved in predominantly c-domain films is useful in increasing the α ME value. It is also believed that the reduced substrate clamping in the PZT film due to the film on the foil structure and the strong interfacial bonding of the PZT/LNO/HfO 2 /Ni heterostructure should allow for better strain transfer and in turn stronger ME coupling between PZT and Ni.…”
