U.S.-France Cooperative Research: Crystal Growth and Spectroscopy of Impurity Substituted Spin-Peierls Materials

这项为期三年的美法材料合作研究奖由宾汉姆顿纽约州立大学的Janice L. Musfeldt和她的团队以及巴黎第十一大学的Alexandre Revcolevschi和他的团队参与。他们的合作旨在研究轻掺杂CuGeO3（铜-锗-氧）晶体的生长和光谱响应作为温度和高磁场的函数。美国小组为这次合作带来了远红外光谱方面的专业知识。这与法国研究者在晶体生长方面的专业知识相辅相成。他将负责使用浮动区技术生长轻取代的单晶。实验将在佛罗里达州塔拉哈西的国家高磁场实验室联合进行。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）提出的联合提案。美国国家科学基金会将支付美国研究人员和研究生的旅费和生活费。法国科学研究中心将支持法国研究人员访问美国。该合作将促进对新型磁性材料（CuGeO3）的基本理解，这种材料与超导铜氧化物和其他掺杂过渡金属氧化物相似。这项工作将引起固体材料界的普遍兴趣。

0089575MusfeldtThis three-year award for U.S.-France cooperative research in materials research involves Janice L. Musfeldt and her group at the State University of New York in Binghamton and Alexandre Revcolevschi and his group at the Universite Paris XI. Their collaboration is aimed at investigations of growth and spectroscopic response of lightly doped CuGeO3 (copper-germanium-oxygen) crystals as a function of temperature and high magnetic field. The US group brings to this collaboration expertise in far-infrared spectroscopy. This is complemented by the French investigator's expertise in crystal growth. He will be responsible for growth of lightly substituted single crystals using the floating zone technique. Experiments at the National High Magnetic Field Laboratory in Tallahassee, Florida will be carried out jointly.This award represents the US side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigators and graduate students. The CNRS will support the visits of French researchers to the United States. The collaboration will advance fundamental understanding of novel magnetic materials (CuGeO3) which have similarities to the superconducting copper oxides and other doped transition metal oxides. The work will be of general interest to the solid state materials community.
