US-Hungary Joint Fund Materials Research on Mossbauer Spectroscopy of High Tc Superconductors

这项由Eotvos大学的Attila Vertes博士和Drexel大学的Amar Nath博士合作的美国-匈牙利研究项目的主要目标是获得对高温超导体Y- Ba-CU-O的基本了解。这种材料的整体特性是由微观层面上发生的事情决定的。穆斯堡尔光谱技术非常适合探测铜氧链和薄片的微环境。这两个铜位点被认为在超导现象中起着重要作用。德雷克塞尔实验室专门研究发射穆斯堡尔技术，超导体中的一小部分铜被钴-57取代。利用铁-57、锡-119和铕-151的吸收穆斯堡尔光谱研究将在埃特沃斯进行。该高温超导项目通过使美国和东欧的领先专家在共同感兴趣和能力强的领域结合互补人才和集中资源，实现了推进科学知识的计划目标。

The primary objective of this US-Hungary research project under between Dr. Attila Vertes, Eotvos University, and Dr. Amar Nath, Drexel University, is to acquire basic understanding of the high-temperature superconductor, Y- Ba-CU-O. The bulk properties of this material are determined by what is happening on the microscopic level. The technique, Mossbauer spectroscopy, is ideally suited for probing the micro-environment of copper-oxygen chains and sheets. Both of these copper sites are believed to play an important role in the superconductivity phenomenon. The Drexel lab specializes in emission Mossbauer technique, where a minute fraction of the copper in the superconductor is substituted by cobalt-57. Investigations using absorption Mossbauer spectroscopy using iron-57, tin-119 and europium-151 will be done at Eotvos. This project in high-temperature superconductivity fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interest and competence.
