Abstract: The transverse magnetoelectric voltage coefficient of piezoelectric-magnetostrictive bilayer at the electromechanical resonance (EMR) was derived according to the constitutive equations of piezoelectric and magnetostrictive phases, and the equation of motion. As a function of frequency, the transverse magnetoelectric voltage coefficients of Tb_1-x Dy_x Fe_2-y (TDF)-Pb(Zr,Ti) O₃ (PZT) bilayer had been calculated using the corresponding material parameters of individual phases. The resonance frequency was calculated using different length and volume fraction of piezoelectric phase, and the dependence of frequency on the two parameters was analyzed. The results indicate that the bilayer shows strong resonance character at resonance frequency. The transverse magnetoelectric voltage coefficient can reach peak value 11.2 V·cm^-1·Oe^-1 at 55.2 kHz when effective mechanical quality factor is 50, which is about 40 times as high as that at the low frequency (281.9 mV·cm^-1·Oe^-1). The resonance frequency rises with shortening the length and increasing the volume fraction of piezoelectric phase. TDF-PZT bilayer is fabricated and the relevant experiment is carried out to verify the calculated results. The actual effective mechanical quality factor is about 48.
