U.S.-Austria Cooperative Research on the Electronic and Magnetic Properties of Quasicrystalline and Amorphous Alloys

该奖项支持内布拉斯加州大学的S.S.Jaswal教授和D.J.Sellmyer教授与维也纳技术大学的J&gt；rgen Hafner教授在凝聚态物理方面进行合作。他们的两个研究小组都对金属玻璃感兴趣，并提议合作研究非晶态和准晶态过渡金属合金。这项合作将把奥地利小组在液态和非晶态金属原子结构方面的理论专业知识与美国小组在电子结构和磁性方面的实验和理论专业知识结合起来。此外，欧洲和美国的其他几个研究小组将加入合作，寻找特别必要的人才。至少有一名年轻的美国科学家，可能是博士后级别的科学家，将参与合作。该项目解决了磁性材料领域的主流问题，并集中讨论了一些特别活跃、重要和有价值的主题。理论和实验工作的结合将有助于更好地理解3D-5D过渡金属玻璃的短程有序性和电子性质。准晶具有非周期的长程有序结构，理论研究难度较大。尽管如此，这种将非晶系理论扩展到由简单金属组成的准晶性质的努力，很有可能提供有价值的新见解。

This award supports Professors S.S. Jaswal and D. J. Sellmyer of the University of Nebraska to collaborate in condensed matter physics with Professor J>rgen Hafner of the Technical University of Vienna. Their two research groups share an interest in metallic glasses and propose to work together in a study of amorphous and quasicrystalline transition-metal alloys. The collaboration will bring together the theoretical expertise of the Austrian group in atomic structure of liquid and amorphous metals with the experimental and theoretical expertise of the U.S. group in the electronic structure and magnetic properties. In addition, several other research groups in Europe and the U.S. will be brought into the collaboration for particular necessary talents. At least one young U.S. scientist, probably on the postdoctoral level, will be involved in the collaboration. This project addresses mainstream issues in the field of magnetic materials, and focuses on some particular active, important and rewarding topics. The combination of theoretical and experimental work should contribute to a better understanding of the short-range order and electronic properties of 3d-5d transition metal glasses. The quasicrystals are much more difficult to study theoretically because of their non- periodic long-range order. Still, this effort to extend the theory on amorphous systems to the properties of quasicrystals made up of simple metals has a good chance of providing valuable new insights.
