The effect of excess iron-doping in piezoelectric lead-zirconate-titanate (PZT) on the microstructure was investigated by means of transmission electron microscopy in conjunction with electron diffraction and energy dispersive x-ray spectroscopy analysis. Electron paramagnetic resonance (EPR) spectroscopy has been used to characterize the site of the iron functional centers. A crystalline secondary magnetic phase formed upon sintering, magnetoplumbite (PbFe{sub 12}O{sub 19}), has been unequivocally identified. Furthermore, the phase assemblage observed in the Fe{sup 3+}-doped PZT 60/40 sample could be correlated with an exchange-coupled resonance in the EPR spectra.
