Superlattices, Multilayers, and Metastable Systems

各种超晶格、多层膜和亚稳态固体将主要通过多源先进溅射沉积来制备，并用X射线衍射、透射电子显微镜等技术进行表征。超晶格和多层膜被设计用来揭示具有不同关联长度的磁性和超导系统中的有限尺寸效应和维度交叉。对磁表面各向异性的实现和起源进行了探讨。将特别注意垂直磁化及其可能与磁致伸缩的联系。在超导体/磁性多层膜中，实验研究了超导电性的影响与磁性层的磁有序和导电性之间的关系。许多亚稳态固体系统将被研究，以揭示用传统方法无法获得的结构的新性质。

A variety of superlattices, multilayers and metastable solids will be fabricated primarily by multi-source advanced sputter deposition, and characteized by x-ray diffraction, transmission electron microscopy and other techniques. The superlattices and multilayers are designed to reveal finite-size effects and dimensional crossover in magnetic and superconducting systems with various correlation lengths. The realization and the origin of magnetic surface anisotropy will be investigated. Paticular attention will be paid toward perpendicular magnetization and its probable connection with magnetostriction. In superconductor/magnetic multilayers, experiments are proposed to investigate the relationship between the effects on superconductivity and the magnetic ordering and conductivity of the magnetic layers. A number of metastable solid systems will be studied in order to reveal new properties in structures unattainable by conventional methods.
