Abstract

A hybrid perovskite material with a Two-dimensional (2D) layered (C₄H₉NH₃)₂PbIBr₃ crystal structure is presented that exhibits magnetoelectricity and piezoelectricity coupling properties at room temperature. The interaction between ferromagnetism and piezoelectricity was achieved by harmonizing their respective ferroic orders. 2D layered organic–inorganic hybrid perovskites demonstrated controlled multifunctional ferroic attributes, with each characteristic established. The magnetic and piezoresponse phase rotation was controlled by modulating the electric-field strength using the magnetoelectricity and piezoelectricity. The responsive and phase-controllable behavior of ferromagnetism and piezoelectricity in 2D hybrid perovskites was effectively managed by an external electric field induced by the coupling between ferroic orders at room temperature. This discovery offers a promising avenue for future research on hybrid perovskites with novel 2D layered-crystal structure.

本文介绍了一种具有二维（2D）层状（C4H9NH3）2PbIBr3 晶体结构的混合包晶材料，它在室温下具有磁电和压电耦合特性。铁磁性和压电性之间的相互作用是通过协调各自的铁阶实现的。二维层状有机-无机杂化包晶展现了可控的多功能铁电属性，每种特性都已确立。利用磁电性和压电性调制电场强度，控制了磁响应和压电响应相位旋转。二维混合包晶石中的铁磁性和压电性的响应和相位可控行为，在室温下由铁阶之间的耦合诱导的外部电场的作用下得到了有效的控制。这一发现为今后研究具有新型二维层状晶体结构的混合包晶提供了一个前景广阔的途径。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
