磁性对局部原子环境高度敏感,这是由纳米结构和纳米薄膜中表面或界面原子与体原子的大比例引起的独特磁性行为的起源。在技术中具有强相关性的一个关键特性是界面诱导的垂直磁化各向异性,其通常在仅几个原子平面的磁性层中观察到。建立这种现象的存在需要一个更好的控制的增长模式,并在其理解的进步需要详细的结构研究加上敏感的磁特性。虽然磁性纳米结构主要是利用分子束外延实现的,但在电解环境中制备磁性纳米结构已经成为可能,其控制程度与在真空中实现的控制程度相当。本文综述了近年来在Au(111)单晶电极上电沉积外延磁性层的研究进展,重点介绍了原位结构和磁性表征。本文还表明,表面磁性是非常敏感的电化学界面。
Magnetism is highly sensitive to the local atomic environment, a property that is at the origin of the unique magnetic behavior induced by the large ratio of surface or interface atoms to bulk atoms in nanostructures and ultrathin films. One key property of strong relevance in technology is interface-induced perpendicular magnetization anisotropy, which often is observed in ultrathin magnetic layers of only a few atomic planes. Establishing the existence of this phenomenon required an improved control of the growth modes, and advances in its understanding required detailed structural studies coupled with sensitive magnetic characterization. While magnetic nanostructures have been mainly realized using molecular beam epitaxy, the preparation of magnetic nanostructures in the electrolytic environment has become possible, with a degree of control that is comparable to that achieved in ultrahigh vacuum. This article reviews recent studies about epitaxial ultrathin magnetic layers electrodeposited on Au(111) single crystal electrodes with emphasis on in situ structural and magnetic characterization. This article also demonstrates that surface magnetism is very sensitive to the electrochemical interface.
