The influence of ferromagnetic phase properties on the magnetoelectric response of hot pressed particulate composites formed by 80mol% of 0.675{[}Pb(Mg1/3Nb2/3)O-3]-0.325{[}PbTiO3] as piezoelectric matrix and 20mol% of NiFe2O4, CoFe2O4 or BaFe12O19 phases was analyzed. The hot pressing sintering method was suitable for obtaining composites with apparent density higher than 94% and electric resistivity close to 10(9) .m, independently of the ferromagnetic phases used. The magnitude of the magnetoelectric coupling seems to be governed by the piezoelectric properties of ferroelectric PMN-PT matrix, and the zero bias magnetoelectric coefficient values are determined by the ferromagnetic hardness of the magnetic phase.
