From: Extraction of Preisach model parameters for fluorite-structure ferroelectrics and antiferroelectrics

Experimental data from a 10 nm ZrO2 sample in excellent agreement with the antiferroelectric model for both saturated and unsaturated double hysteresis loops. The extracted \(P_{s+}\), \(P_{r+}\), \(E_{c+}\), \(E_{c,shift+}\), \(P_{s-}\), \(P_{r-}\), \(E_{c-}\), \(E_{c,shift-}\), \(P_{offset}\), and \(\varepsilon _{AFE}\) are 6.40 μC/cm2, 6.34 μC/cm2, 1.12 MV/cm, 2.39 MV/cm, − 6.61 μC/cm2, − 6.51 μC/cm2, − 1.22 MV/cm, − 2.35 MV/cm, 0.43 μC/cm2, 33.70, respectively.
