Polarization Kinetics in Transparent Pb(Mg1/3Nb2/3)O3–23Pb(Zr0.53Ti0.47)O3 Ceramic

Аннотация

The polarization kinetics in a transparent Pb(Mg_1/3Nb_2/3)O₃–23Pb(Zr_0.53Ti_0.47)O₃ ferroceramic is investigated in the electric fields of 0 < E < 6 kV/cm. The optical transmittance, dielectric, and acoustic properties of ferroceramics are measured at room temperature. The dielectric and acoustic characteristics are found to instantly switch even in fields below the coercive, due to the emergence of a partially ordered ferroelectric phase. Furthermore, the polarized phase arisen in the electric field is not completely stable.
