Abstract

In this work structural, electric, dielectric, and anelastic properties of single phase high density (> 97%) (1-x) PFW-xPT ceramics, with 0 <= x <= 0.30, are investigated. The experimental results show that the temperatures, in which magnetic (T-N) or electric (T-FE) ordering occur, can be interchanged by PbTiO3 addition. Correlations between the experimental results allow to estimate intrinsic ferromagnetoelectroelastic coefficients at the temperatures, where the multiferroic state exist. The intrinsic magnetoelectric coefficient is maximum for compositions, in which the temperatures for magnetic and ferroelectric ordering coincide, no matter in what sequence the orderings (FE or AFM) occur.
