摘要：

Frequency dependent dielectric studies on the mixed system (1-x)Pb(Fe1/2Nb1/2)O-3-xPbTiO(3) reveal contributions from the electrodes, grain boundaries, and grains. It is shown that the intrinsic value of the dielectric permittivity coming only from the grains peaks at x=0.08. Analysis of synchrotron x-ray diffraction profiles using the Rietveld technique shows that this peaking is linked with a monoclinic to tetragonal morphotropic phase transition in the multiferroic system.
