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

这项为期三年的材料研究美法合作研究奖授予纽约州立大学宾厄姆顿分校的Janice L.MusFeldt和巴黎第十一大学的Alexandre Revcolevschi及其团队。他们的合作旨在研究轻掺杂CuGeO_3(铜-锗-氧)晶体的生长和光谱响应随温度和强磁场的函数。这家美国集团将远红外光谱方面的专业知识带到了这次合作中。此外，这位法国研究人员还拥有晶体生长方面的专业知识。他将负责使用浮区技术生长被轻取代的单晶。位于佛罗里达州塔拉哈西的国家强磁场实验室的实验将联合进行。这一奖项代表了美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付美国调查人员和研究生的旅费和生活费。CNRS将支持法国研究人员访问美国。这一合作将促进对新型磁性材料(CuGeO_3)的基础理解，这些材料与超导铜氧化物和其他掺杂的过渡金属氧化物有相似之处。这项工作将引起固态材料界的普遍兴趣。

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.
