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

9419406 Tsen将对磁性薄层中的界面结构和磁畴结构进行研究。 有两个具体的专题和研究方法，即： (1)Co/Cu/Co和Fe/Cr/Fe磁性多层膜界面结构的研究 高分辨电子显微术 (2)Co/Cu和Fe/Cr双层膜磁畴结构的Lorentz显微镜研究 这一建议的结果将提供更好的洞察对我们的理解的Co/Cu/Co和Fe/Cr/Fe系统，最近已被证明表现出巨磁电阻，以及磁电阻的振荡与厚度的增加的中间层。 这些人工超晶格是重要的，因为它们在磁场传感器器件和磁阻读取头的潜在应用。 ***

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. ***
