Magnetic and Transport Properties of High - TC Superconductors

在贝尔格莱德物理研究所的Ljiljana Dobroavljevic和爱荷华州立大学的John Clem在固体物理方面进行的为期三年的美国-南斯拉夫合作研究项目中，研究人员将发展高TC超导体的磁性和输运性质的现象学理论。通过这些研究，研究人员将确定超导的机制(它是如何工作的)，材料中的薄弱环节，以及电流流动的抑制剂。尽管这一领域取得了重大进展，但实验者们仍在寻找这些问题的解释。美国和南斯拉夫的调查人员在理论研究方面处于领先地位。他们的联合研究将对高温超导性能和微观结构产生新的见解。该项目得到了美国-南斯拉夫科学技术合作联合委员会的批准，并由一个由美国和南斯拉夫两国政府提供同等捐款的联合基金提供支助。美国的捐款每年由国务院提供。没有NSF基金参与其中。赠款是给南斯拉夫的主要科学机构，但包括美国科学家前往南斯拉夫旅行的美元资金和南斯拉夫科学家在美国的生活费。

In this three-year U.S.-Yugoslav cooperative research project in solid state physics between Ljiljana Dobrosavljevic of the Institute of Physics in Belgrade and John Clem of Iowa State University, the investigators will develop a phenomenological theory of magnetic and transport properties of high tc superconductors. Through these studies, the investigators will identify the mechanism for superconductivity (how does it work), weak links in the materials, and inhibitors to electrical flow. Despite the significant advances in this field, experimentalists are searching for explanations to these problems. The U.S. and Yugoslav investigators are among the leaders in theoretical research. Their joint research will yield new insights into high tc superconducting properties and microstructure. This project was approved by the U.S.-Yugoslav Joint Board on Cooperation in Science and Technology and is supported through a joint fund consisting of matching contributions from the governments of the United States and Yugoslavia. The U.S. contribution is provided annually by the Department of State. No NSF funds are involved. Grants are made to the principal scientific institution in Yugoslavia, but include dollar funds for U.S. scientist travel to Yugoslavia and for Yugoslav scientists' living expenses in the U.S.
