Terfenol-D disk/Pb(Zr,Ti)O-3 (PZT) ring multiferroic heterostructures were prepared and the magnetoelectric properties were characterized, for which PZT piezoelectric ring was poled radially. When the outer/inner diameter ratio of PZT ring was 1.6 and the bias and alternative magnetic fields were perpendicular to the thickness direction, the highest magnetoelectric voltage coefficient (dV/dH) at 1 kHz of 165 mV Oe(-1) was obtained, which was much higher than that for the previously reported disk-ring heterostrucutres with the piezoelectric phase poled along the thickness direction (75 mV Oe(-1)). The enhanced magnetoelectric properties of the present heterostructures were due to the larger component of the piezoelectric coefficient and the increased effective length of the piezoelectric phase that contributed to the magnetoelectric coupling.
