Abstract
Composites of BaTiO3 and CoFe2O4 have been prepared with various compo sitions by double sintering method. The presence of the two phases has been confirmed by XRD. Variation of dielectric constant with temperat ure in these samples has been studied. All the samples have shown line ar magnetoelectric conversion in the presence of static magnetic field . The magnetoelectric effect (dE/dH) has been studied as a function of intensity of magnetic field. The maximum value of the conversion fact or (dH/dH)(max) was found to be 0.16 mV/cm/Oe.
