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. *** //

该奖项由美国-阿根廷合作科学计划授予，支持圣地亚哥州立大学的 Saul Oseroff 博士和阿根廷里奥内格罗巴里洛切原子中心 (CAB) 的 Manuel Tovar 博士进行的材料科学研究。 该项目重点研究掺杂R2CuO4化合物的磁性能和超导性能的相关性。 该项目的重点是寻找弱铁磁成分（WF）的出现与较重的稀土铜酸盐中超导性丧失之间的相关性。 掺杂 Ce 或 Th 的化合物不会成为超导体。 提出了一系列实验，包括涉及静水压力和轴向压力对磁性能和超导性能的影响的实验。 该项目延续了两个有能力、富有成效的团队之间积极、成功的合作。 *** //
