U.S.-Brazil Cooperative Research: Electronic and Magnetic Properties of Novel Materials

这项美国-巴西奖将支持巴西博士之间的研究合作。圣地亚哥州立大学的米尔顿·托里卡奇维利和亚历克斯·拉瑟达与圣地亚哥大学的博士合作。Renato de Figueiredo Jardim和Sergio Gama分别来自圣保罗大学和坎皮纳斯大学，研究新型材料的电子和磁性。具体来说，他们将研究强相关电子系统（SCES）的输运、磁性和热力学性质，以及显示大磁阻效应的过渡金属氧化物。研究将在低磁场下进行，以及在高磁场和低温的极端条件下对高质量样品进行研究，目的是提高对这些材料的理解并测试现有模型。此次合作将结合圣地亚哥州立大学、洛斯阿拉莫斯国家强磁场实验室、圣保罗大学和坎皮纳斯大学的资源、设施和专业知识。这两所巴西大学支持拉丁美洲凝聚态物质研究的最大努力之一。在洛斯阿拉莫斯，pi们将获得60特斯拉准连续磁铁的使用权，这是世界上最强大的可控功率磁铁，也是美国首个此类磁铁。美国pi带来了他们在极端条件下进行电子和磁性测量的丰富经验。伽马教授在研究磁性材料的相关系方面很有经验。Jardim博士将在整个项目中培训新学员。＊＊＊

9725929 Torikachvili This U.S.-Brazil award will support a research collaboration between Drs. Milton Torikachvili and Alex Lacerda of San Diego State University to work with Drs. Renato de Figueiredo Jardim and Sergio Gama at the University of Sao Paulo and the University of Campinas, respectively, on electronic and magnetic properties of novel materials. Specifically, they will study transport, magnetic, and thermodynamic properties of strongly correlated electron systems (SCES), and transition metal oxides displaying large magnetoresistive effects. The studies will be done in low magnetic fields, as well as in extreme conditions of high magnetic fields and low temperatures on high quality specimens, with the goal of advancing the understanding of these materials and to test current models. This collaboration will combine the resources, facilities and expertise of San Diego State University, the National High Magnetic Field Laboratory at Los Alamos, the University of Sao Paulo and the University of Campinas. The two Brazilian universities support one of the largest efforts in condensed matter research in Latin America. At Los Alamos, the PIs will be given access to the 60 tesla quasicontinuous magnet, which is the world's strongest controlled power magnet and the first one of its kind in the US. The US PIs bring their extensive experience in performing measurements of electronic and magnetic properties at extreme conditions. Professor Gama is experienced in the study of phase relations in magnetic materials. Dr. Jardim will be training new students throughout this project. ***
