    In this study, we report results on magnetoelectric (ME) core-shell Pb(Zr,Ti)O(3) (PZT)-NiFe(2)O(4) (NF) particulate nanocomposites. NF particles forming the shell had size in range of 20-30 nm. The grain size of sintered nanocomposites was found to be in the range of 500-800 nm. The sintered nanocomposite exhibited piezoelectric coefficient (d(33)) of 60 pC/N, dielectric constant of 865, and ME coefficient of 195 mV/cm Oe. High ME coefficient was observed for wide range of dc bias magnetic field. This approach of fabricating layered composite has a promise to provide large ME coefficients in particulate sintered structures.
