  • Abstract
    Multiferroic solid solutions between Pb(Fe2/3W1/3)O3 (PFW) and PbTiO3 (PT) [PFW-PT] have been characterized by anelastic measurements. Anomalies in the temperature dependence of the elastic constants have been observed at TN and TC for all samples, indicating that the magnetoelectric coupling (ME) between the ferroelectric and antiferromagnetic orders occurs “via strain”. A numerical approximation for the ME coefficients was obtained from the eletroelastic and magnetoelastic coefficients and the values of electric and magnetic susceptibility. These coefficients are greater the closer the temperatures of AFM and FE orders are with each other.
