多铁性材料中的磁电性:理论展望

Magnetoelectricity in Multiferroics: a Theoretical Perspective

Shuai Dong, Hongjun Xiang, Elbio Dagotto

摘要:

多铁性材料的关键物理性质是磁性和极化之间的耦合,即磁电性。磁电的起源和表现在现有的多铁性系统中可能非常不同,在现象背后隐藏着多种可能的机制。在这篇综述中,我们从理论的角度描述了引起磁电的基本物理。本文主要介绍单相多铁性材料和磁电异质结构的主流物理机制。最新的趋势解决可能的新磁电机制也将简要概述。

英文摘要:

The key physical property of multiferroic materials is the existence of a coupling between magnetism and polarization, i.e. magnetoelectricity. The origin and manifestations of magnetoelectricity can be very different in the available plethora of multiferroic systems, with multiple possible mechanisms hidden behind the phenomena. In this Review, we describe the fundamental physics that causes magnetoelectricity from a theoretical viewpoint. The present review will focus on the main stream physical mechanisms in both single phase multiferroics and magnetoelectric heterostructures. The most recent tendencies addressing possible new magnetoelectric mechanisms will also be briefly outlined.
