Colossal Intrinsic Magnetoelectric Effect In Pb(fe 2/3w 1/3) 0.83ti 0.17o 3

Dielectric and magnetic properties were investigated in Pb(Fe 2/3W 1/3) 0.83Ti 0.17O 3 ceramics. The dielectric constant in these samples exhibits colossal changes at the magnetic ordering temperature under the presence of bias external electric fields, which presents a close connection with magnetoelectrics effects (ME), confirming the possibility to control magnetic proprieties with electric fields. The ferroelectromagnetoelastic coefficient was determined from the dielectric response as a function of the electric field. The analysis of magnetic and dielectric susceptibilities based on the Landau-Devonshire thermodynamic formalisms indicates that the ME effects is a contribution of intrinsic ME coupling and a field dependent term. © 2012 American Institute of Physics.1019Eerenstein, W., Mathur, N.D., Scott, J.F., Multiferroic and magnetoelectric materials (2006) Nature, 442 (7104), pp. 759-765. , DOI 10.1038/nature05023, PII NATURE05023Smolenskii, G.A., (1982) Usp.
