摘要: Dielectric and magnetic properties were investigated in Pb(Fe2/3W1/3)0.83Ti0.17O3 ceramics. The dielectric constant these samples exhibits colossal changes at the ordering temperature under presence of bias external electric fields, which presents a close connection with magnetoelectrics effects (ME), confirming possibility to control proprieties fields. ferroelectromagnetoelastic coefficient was determined from response as function field. analysis susceptibilities based on Landau-Devonshire thermodynamic formalisms indicates that ME is contribution intrinsic coupling field dependent term.
