We comparatively investigate the influence of various high-permeability alloys on the hysteretic and remanent resonant magnetoelectric(ME) response in a composite of magnetostrictive nickel(Ni) and piezoelectric Pb(Zr1-x, Tix)O3(PZT). In order to implement this comparative research, Co-based amorphous alloy(CoSiB), Fe-based nanocrystalline alloy(FeCuNbSiB) and Fe-based amorphous alloy(FeSiB) are used according to different magnetostriction(λs) and saturation magnetization(μ0Ms) characteristics. The bending and longitudinal resonant ME voltage coefficients(αME,b and αME,l)are observed comparatively for CoSiB/Ni/PZT, FeCuNbSiB/Ni/PZT, and FeSiB/Ni/PZT composites. The experimental data indicate that the FeSiB/Ni/PZT composite has the largest remanent self-biased αME,band αME,ldue to the largest magnetic grading of λs and μ0Ms in the FeSiB/Ni layer. When the number of FeSiB foils is four, the maximum remanentαME,b and αME,l at zero bias magnetic field are 57.8 V/cm·Oe and 107.6 V/cm·Oe, respectively. It is recommended that the high-permeability alloy is supposed to have larger λs and μ0Ms for obtaining a larger remanent self-biased ME responses in ME composite with high-permeability alloy.

The experimental data indicate that the FeSiB / Ni / PZT composite (αME, b and αME, l) were observed for both CoSiB / Ni / PZT, FeCuNbSiB / Ni / PZT, and FeSiB / Ni / has the largest remanent self-biased αME, band αME, ldue to the largest magnetic grading of λs and μ0Ms in the FeSiB / Ni layer. When the number of FeSiB foils is four, the maximum remanentαME, b and αME, l at zero bias Magnetic fields are 57.8 V / cm · Oe and 107.6 V / cm · Oe, respectively. It is recommended that the high-permeability alloy is supposed to have larger λs and μ0Ms for obtaining a larger remanent self-biased ME responses in ME composite with high-permeability alloy.
