Dielectric and magnetic properties were investigated in Pb(Fe2/3W1/3)O-3-PbTiO3 ceramics. The dielectric constant in these materials exhibits changes at the magnetic ordering temperature, which presents a close connection with the magnetoelectric intrinsic effect (ME). An approximation of the ferroelectromagnetoelastic coefficient was determined from the dielectric susceptibility response. The analysis of magnetic and dielectric susceptibilities based on the Landau-Devonshire thermodynamic formalisms indicates that the ME effects is larger (in absolute value) when the FE and AFM transitions are close together.
