Non-steady-state optothermal electromotive force in relaxor ferroelectrics
Abstract We predict a new non-steady-state optothermal electromotive force effect in relaxor ferroelectrics. The effect is observed and studied in a PbNi $$_{1/3}$$ Ta $$_{2/3}$$ O $$_3$$ crystal at light wavelength $$\lambda =532$$ nm and room temperature, which is significantly above the broad, fr...

| description | Abstract We predict a new non-steady-state optothermal electromotive force effect in relaxor ferroelectrics. The effect is observed and studied in a PbNi $$_{1/3}$$ Ta $$_{2/3}$$ O $$_3$$ crystal at light wavelength $$\lambda =532$$ nm and room temperature, which is significantly above the broad, frequency-dependent maximum of the permittivity ( $$T_m\simeq 89$$ K), below which remanent polarization and the relaxor ferroelectric state arise. We focus on the pronounced mismatch in high-frequency behaviour of the non-steady-state EMF and conductivity response due to nonuniform laser heating and develop the ensuing theory of the effect. |
