ABSTRACT Multiferroic materials exhibits at least two properties among ferroic parameters i.e. ferroelectricity, ferromagnetism, and ferroelasticity. Single phase materials which show at least two ferroic properties at a time are very rare. This is because in most ferroelectrics, the mechanism is due to hybridization of empty d-orbital of metal ion and occupied p-orbital of the oxygen ion, causing lack of multiferroic phenomenon. Multiferroics are also magnetoelectric material, in which the phenomenon of coupling between ferroelectric and magnetic order coexist which has a potential application in memory  devices, sensors, actuators etc. Recent research activities of manipulating electric field by magnetic field will be discussed. Beginning with the history of Magnetoelectric (ME) effect, limitations of single phase Magnetoelectric compound and need of ME compositesis discussed. Few important works of laminate composite is also discussed. Finally the review ends with proposed applications of ME composites following with some future perspectives.
