**6. Conclusion**

In summary, it is understood from the experimental studies that the magnetoelectric coefficient (*<sup>δ</sup><sup>E</sup> <sup>δ</sup>H*) of a composite can be increased, using individual phases with higher piezoelectric and higher magnetization values. It was found that the soft piezoelectric phase can increase the ME value and higher Zinc doping was found to improve the magnetoelectric response of PZT – CFO based magnetoelectric composite. The coercive field of the CZF particles was lower than the CFO particles, which contributes towards the easy reversal of magnetic domain under AC magnetic field. The addition of Zn, contributes to the increase in saturation magnetization and hence the permeability. It has already reported that with high magnetic permeability inside the ferromagnetic material, magnetic flux strength increases and hence it helps to increase the effective piezomagnetic coefficient (dλ/dH). This increase in piezomagnetic coefficient helps to improve the magnetoelectric coefficient of the composites.
