The magnetoelectric effect in millimeter size PMN-PT/Terfenol-D composites is known. In an effort towards miniaturization, we report on the magnetoelectric effect in micrometer-size sputtered composites. Multilayers of TbFe/FeCo with a thickness of 4 Am were sputter deposited on both sides of PMN-PT piezoelectric single crystals. The magnetoelectric voltage of samples was measured and reached values of 13 mV / (Oe cm) at dc bias fields of 2 mT, a linear dependence of magnetoelectric voltage on ac amplitude was detected in the range from 1 mT to 1 nT.
