U.S.-Argentina Cooperative Science Program: Correlation of the Magnetic and Superconducting Properties of the R2Cu04 Compounds

这项由美国-阿根廷合作科学计划颁发的奖项支持由圣地亚哥州立大学的Saul Oseroff博士和阿根廷里约内格罗河原子中心(CAB)的Manuel Tovar博士进行的材料科学研究。该项目的重点是研究掺杂的R2CuO4化合物的磁性和超导性能之间的相关性。该项目的中心是找到较重稀土铜酸盐中弱铁磁成分(WF)的出现与超导电性损失之间的联系的可能性。当掺入Ce或Th时，化合物不会成为超导体。提出了一系列实验，包括流体静压和轴向压力对磁性和超导性能的影响。该项目继续在两个有能力和富有成效的群体之间进行积极和成功的合作。*//

This award from the U.S.- Argentina Cooperative Science Program supports research in materials science to be conducted by Dr. Saul Oseroff of San Diego state University and Dr. Manuel Tovar of the Centro Atomico Bariloche (CAB), Rio Negro, Argentina. The project focuses on the study of correlation of the magnetic and superconducting properties of doped R2CuO4 compounds. The project centers on the possibility of finding a correlation between the appearance of a weak ferromagnetic component (WF) and loss of superconductivity in the heavier rare-earth cuprates. Compounds, which when doped with Ce or Th, do not become superconductors. A series of experiments are proposed including ones involving the effects of hydrostatic and axial pressure on the magnetic and superconducting properties. The project continues an active and successful collaboration between two able and productive groups. *** //
