Characterization of Mn-modified Pb (Mg13 Nb23)O 3 -PbZrO3 -PbTiO3 single crystals for high power broad bandwidth transducers

Journal Article


Abstract


  • The effect of MnO2 addition on the dielectric and piezoelectric properties of 0.4Pb (Mg13 Nb23) O3 -0.25PbZr O3 -0.35PbTi O3 single crystals was investigated. Analogous to acceptor doping in "hard" Pb (Zr,Ti) O3 based polycrystalline materials, the Mn doped crystals exhibited enhanced mechanical Q (���1050) with low dielectric loss (���0.2%), while maintaining ultrahigh electromechanical coupling k33 >90%, inherent in domain engineered single crystals. The effect of acceptor doping was also evident in the build-up of an internal bias (Ei ���1.6 kVcm), shown by a horizontal offset in the polarization-field behavior. Together with the relatively high usage temperature (TR-T ���140 ��C), the Mn doped crystals are promising candidates for high power and broad bandwidth transducers. �� 2008 American Institute of Physics.
