US-UK Cooperative Research: Interdependence of Micro- structure and Magnetic Properties in Iron-Based Thin Films

该奖项将支持阿拉巴马大学的John Barnard博士和英国利弗波尔大学冶金与材料工程系的Peter Goodhew博士在冶金方面的合作研究。该项目将重点研究铁基二元合金薄膜的微观结构随工艺条件和热处理的变化。到目前为止，巴纳德博士参与了关于溅射薄膜生长和磁测量表征这一主题的大量工作。在这个项目中，他将在利物浦对两个铁基薄膜系统--Fe-N和Fe-Sn--随温度的变化进行微观结构和结晶学表征。巴纳德博士将直接与古德休博士和他的团队成员合作，以掌握分析性的透射电子显微镜技术，然后将其引入阿拉巴马大学的新的透射电子显微镜设施。古德休博士在分析和高分辨率电子显微镜方面拥有丰富的专业知识。此外，利物浦大学拥有卓越的显微镜设备。这一研究结果可以为揭示非晶态短程有序的本质，以及确定该体系的晶化结构动力学提供依据。

This award will support collaborative research in metallurgy between Dr. John Barnard, University of Alabama and Dr. Peter Goodhew, Department of Metallurgical and Materials Engineering, University of Liverpoool, U.K. The project will focus on microstructural characterization by Transmission Electron Microscopy (TEM) of iron-based binary alloy thin films as a function of processing conditions and thermal treatment. Dr. Barnard has been involved to date in substantial work on the topic of thin film growth by sputtering and characteriza- tion by magnetometry. In this project he will undertake in Liverpool microstructural and crystallographic characterization of two Fe-based thin film systems, Fe-N and Fe-Sn as a function of temperature. Dr. Barnard will work directly with Dr. Goodhew and members of his group in order to master analytic TEM techniques, which can then be introduced to the University of Alabama's new TEM facility. Dr. Goodhew has extensive expertise in analytical and high resolution electronmicroscopy. In addition, Liverpool University has exceptional microscopy facilities. The results of this research could provide insights into the nature of the short- range order in the amorphous state, as well as defining the structural kinetics of crystallization in this system.
