Webbantiferroelectricity were found in the solid solutions [5]. In 1954, Jaffe et al. studied the piezoelectric properties of PbTiO3 –PbZrO3 solid solution ceramics, and found that its piezoelectric constants were twice as high as that of BaTiO3 , and its Curie temperature (above which the piezoelectricity disappears) was over 300 ∘ C [6]. Now, Webb9 juli 2024 · Here, we discover that besides ferroelectrics, the antiferroelectrics based on Landau switches also have intrinsic negative capacitance effect. We report both the …
