(a) Plots of pyroelectric current J along [100] versus temperature under various prepolarizing electric fields, where dashed lines indicate peak positions. (b) Plots of electric polarization P along [100] versus temperature, obtained by integrating the pyroelectric current with respect to time. (c) Plots of pyroelectric coefficient p versus temperature, where dashed lines indicate peak positions.
