U.S.-France Cooperative Research: Synthesis and Characterization of Rare Earth-3d Transition Metal Magnet Alloy

这个为期三年的奖项为旨在开发高性能磁体的美法合作研究提供支持。这项合作包括密苏里大学的William J. James和法国格勒诺布尔高等师范学院的Philippe l'Heritier的研究小组。研究人员将重点研究稀土过渡金属合金的合成和表征。氮、碳和硼将被插入，产生的化合物将通过磁、热和x射线测量进行分析和表征。美国研究人员将使用中子衍射来提供特定地点的信息和有关磁结构的信息。法国调查人员将使用x射线衍射进行热分析。美国研究人员为这次合作带来了磁性表征和中子衍射技术方面的专业知识。法国在化学和热分析以及低温x射线研究方面的专业知识补充了这一点。该项目将促进对开发高能磁铁所需的磁性结构的理解。

This three-year award provides support for US-France cooperative research aimed at the development of high performance magnets. The collaboration involves the research groups of William J. James at the University of Missouri at Rolla and Philippe l'Heritier of the Ecole Normale Superieure de Physique, Grenoble, France. The investigators will focus on the synthesis and characterization of rare earth transition metal alloys. Nitrogen, carbon and boron will be inserted interstitially and the resulting compounds will be analyzed and characterized by magnetic, thermal and x-ray measurement. The US investigators will employ neutron diffraction to provide site-specific information and information about magnetic structure. The French investigators will carry out the thermal analysis using x-ray diffraction. The US investigators bring to this collaboration expertise in magnetic characterization and neutron diffraction techniques. This is complemented by French expertise in chemical and thermal analyses and in low temperature x-ray studies. The project will advance understanding of the magnetic structure needed for the development of high energy magnets.
