摘要：

Magnetoelectric composites with compositions xBa(0.8)Pb(0.2)TiO(3)+(l -x)Ni0.5CO0.5Fe2O4 in which x varies as 0, 0.55, 0.70, 0.85 and 1.0 were prepared by double sintering method. The presence of single phase in x=0 and x=1 as well as two phases in x=0.55, 0.70 and 0.85 composites has been confirmed by XRD. The dielectric constant and loss tangent were studied as a function of frequency and temperature. The static value of the magnetoelectric conversion factor, i.e. d.c. (ME)(H), was studied as a function of the magnetic field. The maximum value of ME coefficient was observed for x=0.85 composite, whereas minimum for x=0.55 composite.
