9419406 Tsen A study of interface structure and magnetic domain structure in magnetic thin layers will be undertaken. Two specific topics and methods are targeted for study, namely: (1) Investigation of Interface Structure in Co/Cu/Co and Fe/Cr/Fe Magnetic Multilayers by High-Resolution Electron Microscopy; (2) Studies of Magnetic Domain Structure in Co/Cu and Fe/Cr Bilayers by Lorentz Microscopy. The results of this proposal will provide better insight toward our understanding of the Co/Cu/Co and Fe/Cr/Fe systems which have recently been shown to exhibit giant magnetoresistance as well as the oscillation of magnetoresistance associated with increasing thickness of the nonmagnetic interlayer. These artificial superlattices are important due to their potential applications in magnetic field sensor devices and magnetoresistive read heads. ***

9419406将对磁性薄层中的界面结构和磁畴结构进行研究。(1)用高分辨电子显微镜研究了Co/Cu/Co和Fe/Cr/Fe磁性多层膜的界面结构；(2)用洛伦兹显微镜研究了Co/Cu和Fe/Cr双层膜的磁畴结构。这一建议的结果将为我们更好地理解Co/Cu/Co和Fe/Cr/Fe系统，这两个系统最近被证明表现出巨磁电阻以及与非磁性中间层厚度增加相关的磁阻振荡。这些人工超晶格因其在磁场传感器器件和磁阻读取头中的潜在应用而具有重要意义。***
