Magnetoelectric materials possess coupling between the ferroic properties polarization, and magnetization [1, 2, 3, 4]. The interrelation between ferroelectricity and magnetization allows the magnetic control of ferroelectric properties and vice versa. Single phase magnetoelectric (ME) materials (such as Cr2O3, BiFeO3, YMnO3, etc.) suffer from the drawback that ME effect is weak [5, 6, 7]. Better alternatives are ME composites that have higher magnitudes of the ME voltage coefficient exploiting the product property of the materials [8, 9, 10]. Magnetoelectric (ME) effect in a particulate sintered composite was obtained by combining magnetostrictive and piezoelectric phases [11, 12, 13, 14, 15]. Sintered composites have many advantages, such as simplicity in synthesis, cost-effective materials and fabrication process, and better control of desired geometry. However, the ME response is low of the order of 100 mV/cm Oe. Recently, laminated magnetoelectric (ME) composites...
