Scaling behavior of an antiferroelectric hysteresis loop

Abstract

A double hysteresis loop of an antiferroelectric betaine phosphate-arsenate mixed crystal (BP(0.9)A(0.1)) was studied as a function of applied frequency Omega and field amplitude E-0. A scaling analysis of the antiferroelectric hysteresis loop was given to show A(H) proportional to(E-0-E-c)(0.50)Omega(0.40), where A(H) represents the area of the hysteresis loops and E-c a threshold field for observing the hysteresis curves. The scaling exponents are found to be close to the reported theoretical results of the two-dimensional ferromagnetic Ising models. We have also found a different scaling behavior for the antiferroelectric minor loops as A(m) proportional to(E-0-E-c)(2.12)Omega(0.28), where A(m) represents the area of the minor loops.
