WebbThese findings resolve the mystery of the origin of antiferroelectricity in lead zirconate and suggest an approach to the treatment of complex phase transitions in ferroics. 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. After cooling through a first-order phase transition at TA~ 500 K, the structure changes … Visa mer For information on the lattice vibration softening in the high-temperature phase, we examined the Σ, Γ and R points of the Brillouin zone, using … Visa mer
