The property degradation observed in thin Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PMN–PT) crystals is believed to relate to large domains and subsequent clamping induced by the surface boundary. In this work, the properties were investigated as function of domain size, using controlled poling. The degraded piezoelectric and dielectric properties of thin PMN–PT were found to...
Electric fatigue tests have been conducted on pure and manganese-modified Pb(In 0.5 Nb 0.5 )O 3 –Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PIN–PMN–PT) single crystals along different crystallographic directions. Polarization degradation was observed to suddenly occur above 50–100 bipolar cycles in 〈110〉 oriented samples, while 〈001〉 oriented samples exhibited...
PIN-PMN-PT (Pb(Infrac12Nbfrac12)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3) single crystals with 26%-59% PIN were successfully grown by Bridgman technique. Elastic, dielectric and piezoelectric properties of ternary PIN-PMN-PT crystals were studied in comparison with PMN-PT (Pb(Mg1/3Nb2/3)O3 - PbTiO3) crystals. It was demonstrated that PIN-PMN-PT crystals possess as excellent piezoelectric properties as PMN-PT crystals,...
