| Abstract | |
Lead-based multiferroics perovskites with nominal compositions Pb(Fe1/2Nb1/2)O-3 and Pb(Fe2/3W1/3)O-3 were synthesized following a two-stage method. Magnetic proprieties were investigated and correlated to anelastic proprieties, measured by the conventional pulse-echo method. The discussions are focused in the region around 250 K, where magnetoelectroe-lastic instabilities have been observed. X-ray absorption near-edge structure (XANES) study further indicates that the edge position varies with temperature revealing a fluctuation on the valence of iron ions with the temperature, which can be related to a variation in anelastic and magnetic proprieties.
