Magnetic Superlattices and Interfaces

我们认为，人工制备薄膜的物理性质受到所采用的合成和加工方法的强烈影响，因此结构和化学表征必须在对此类薄膜进行的所有研究中发挥关键作用。我们计划使用最先进的技术，如溅射和分子束外延，合成新型磁性薄膜，然后使用多种方法表征其结构和化学成分。生长和表征研究将与物理性质相关，特别是磁输运和磁化。这些研究将涉及到超晶格和界面的磁性，其中两个问题——巨磁电阻和交换偏置——将受到特别的关注。

We believe that the physical properties of artificially-prepared thin films are strongly affected by the synthesis and processing methods employed and therefore structural and chemical characterization must play a key role in all research performed on such films. We plan to synthesize novel magnetic thin films using state-of-the-art techniques such as sputtering and molecular-beam epitaxy, then characterize the structure and chemical composition using a wide variety of methods. Growth and characterization studies will be correlated with physical properties, especially magnetotransport and magnetization. The studies will relate to the magnetism of superlattices and interfaces with two problems - giant magneto-resistance and exchange bias - receiving particular attention.
