多铁性材料BiFeO3的磁学、电学性质及磁电耦合效应
Magnetism, Ferroelectricity and Magnetoelectric Coupling of Multiferroic BiFeO3
摘要
Abstract
The coexistence and coupling of the electric and magnetic order parameters can provide a novel platform to probe magne-toelectric effects in multiferroics. The potential applications of magnetoelectric coupling on future high-density, high-speed and low-energy-cost electronic devices stimulate material scientists and condense matter physicists to revisit multiferroic systems over the past decades. Owing to the high ferroelectric and Néel transition temperatures, BiFeO3 (BFO) appears to be one of the most promising candidates in the on-chip integrated magnetoelectronic devices and attracts people’s interests since 1960s. Especially, the appearance of high-quality BFO epitaxial thin films in 2003 has triggered the study of its intrinsic properties and physics behind. This article re-views the BFO research history and focuses on the cutting-edge achievements in BFO-related projects in the past decade. We mainly introduce the emerging physical phenomena from the aspects of crystalline structures, electrical/magnetic behaviors and magnetoelec-tric coupling in this multiferroic BFO, accompanying with a brief outlook in the conclusion.关键词
