9815138LongThis three-year award for US-France cooperative research in materials science involves Gary Long and a graduate student from the University of Missouri at Rolla and Olivier Isnard of the Laboratoire de Cristallographie, Universite de Grenoble. Their research is focused on electronic and magnetic interactions in intermetallic compounds. The researchers will determine the electronic and magnetic properties of rare earth compounds and their hydrides. The presence of hydrogen or deuterium in these compounds is known to dramatically change their magnetic properties. How these changes are produced by the presence of hydrogen will advance understanding of magnetic interactions in rare earth permanent magnets.This collaboration takes advantage of complementary Mossbauer Effect Laboratories in the US and France. The US researcher brings to this collaboration expertise in the synthetic, magnetic, and structural studies. This is complemented by French expertise in spectral analysis techniques.

9815138这个为期三年的美法材料科学合作研究奖项涉及加里·朗和密苏里大学罗拉分校的一名研究生，以及格勒诺布尔大学结晶学实验室的奥利维尔·伊斯纳德。他们的研究重点是金属间化合物中的电子和磁性相互作用。研究人员将确定稀土化合物及其氢化物的电子和磁性。众所周知，这些化合物中氢或氢的存在会极大地改变它们的磁性。氢的存在如何产生这些变化将促进对稀土永磁体中磁相互作用的理解。这一合作利用了美国和法国互补的穆斯堡尔效应实验室。这位美国研究人员将合成、磁性和结构研究方面的专业知识带到了这次合作中。这与法国在光谱分析技术方面的专业知识相辅相成。
