Study of Interface Structure & Magnetic Domain Structure in Magnetic Thin Layers

[919406]曾森将对磁性薄层的界面结构和磁畴结构进行研究。主要研究两个主题和方法：(1)用高分辨率电子显微镜研究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Co/Cu和Fe/Cr双分子层的磁畴结构。这一建议的结果将为我们对Co/Cu/Co和Fe/Cr/Fe体系的理解提供更好的见解，这些体系最近被证明表现出巨大的磁阻，以及与非磁性中间层厚度增加相关的磁阻振荡。这些人工超晶格在磁场传感器器件和磁阻读头中具有潜在的应用价值。＊＊＊

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. ***
