Popis:	Magnetoelectric resonance behaviour of xCoFe2O4–(1−x)PbTiO3 (x = 0·3,0·4,0·5,0·6) composites synthesised by a sol–gel process was investigated. A smaller electric field of 3 V cm−1 results in an inverse magnetostriction due to a mechanical deformation of piezoelectric phase. The converse magnetoelectric effect (CME) with driving frequency in a range of 5–16 kHz were measured at room temperature. The composite of 0·4CoFe2O4–0·6PbTiO3 exhibits a maximum CME coefficient at electromechanical resonance frequency of 13 kHz. It was found that the low coercivity is advantageous for enhancing CME coefficient. Such a magnetoelectric behaviour controlled by a smaller electric field provides great opportunities for electric field tunable microwave devices.
