Abstract
The dielectric constants of lead iron niobate (PFN) and 40% lead zinc niobate (PZN) added to lead iron niobate (PFN0.6-PZN0.4) have been measured as a function of pressure up to 6 GPa under isothermal conditions between room temperature and 348 K. The relaxor transition temperature measured at 1 kHz excitation frequency varies at a rate −24.5 K/GPa for PFN and at a rate of −28.8 K/GPa for the PFN0.6-PZN0.4 composition.
