Webb4 sep. 2024 · Origin of the Large Negative Electrocaloric Effect in Antiferroelectric PbZrO3. We have studied the electrocaloric response of the archetypal antiferroelectric PbZrO3 … Unexpectedly, our data suggest that there is no critical softening in the lattice except for the Γ relaxational mode. Therefore, the next objective becomes the understanding of the relationship between this critical process and other observed phenomena, namely, (1) the anomalous dispersion and non-critical softening of … Visa mer At high temperatures, PZ has the ideal cubic perovskite structure shown in Fig. 1a.
