Abstract

The contribution of copper and indium cationic sublattices on polarization hysteresis loops in CuInP2S6 van der Waals ferrielectrics has been studied within the quantum anharmonic oscillator model that considers the ordering dynamics of Cu+ cations in the double-well local potential and displacive dynamics of In3+ cations in the three-well shaped potential. The multiple polarization states are manifested as single, double, and triple P(E) hysteresis loops. The triple loops originate from a field-induced ferrielectric to ferroelectric phase transition within a certain range of the phase diagram with continuous increase in the spontaneous polarization below the second-order transition from the paraelectric phase to the ferrielectric state.

阳离子亚晶格参与 CuInP2S6 铁电体的多重极化态

我们在量子非谐振子模型中研究了铜和铟阳离子亚晶格对 CuInP2S6 范德华铁电体中极化磁滞回线的影响，该模型考虑了 Cu+ 阳离子在双阱局部电势中的有序动力学和 In3+ 阳离子在三阱形电势中的位移动力学。多重极化状态表现为单、双和三重 P(E) 滞后环。三重磁滞回线源于在相图的一定范围内由磁场诱导的铁电到铁电的相变，自发极化在从准电态到铁电态的二阶转变以下持续增加。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
