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>rgen Hafner教授在凝聚态物理学方面的合作。他们的两个研究小组对金属玻璃有共同的兴趣，并提议合作研究非晶和准晶过渡金属合金。此次合作将把奥地利研究小组在液态和非晶态金属原子结构方面的理论专长与美国研究小组在电子结构和磁性方面的实验和理论专长结合起来。此外，还将引进欧洲和美国的其他几个研究小组，以培养特定的必要人才。至少有一名年轻的美国科学家，可能是博士后，将参与这项合作。本项目探讨磁性材料领域的主流问题，并着重于一些特别活跃、重要和有价值的课题。理论与实验的结合将有助于更好地理解3d-5d过渡金属玻璃的近程序和电子特性。准晶体由于具有非周期性的长程有序，理论上的研究要困难得多。尽管如此，将非晶系统的理论扩展到由简单金属组成的准晶体的性质的努力，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.
