Magnetoelectric (ME) composite structures of Pb(Zr 0.52 Ti 0.48 )O 3 (PZT) and CoFe 2 O 4 (CFO) were prepared by directly growing PZT films on highly dense CFO ceramics via a simple solution spin coating, rather than by conventional high‐temperature cofiring. An obvious ME response, which had the same bias‐dependent trend as the piezomagnetic coefficient of CFO ceramics, was observed in such film‐on‐bulk ceramic composites. It was found that the PZT films showed a good ferroelectric feature, and the ME response of the composites strongly depended on the resistivity of the CFO ceramics as both a substrate and a bottom electrode. The results suggest plenty of room for further enhancing the ME response of such films‐on‐ceramic substrate composites.
