U.S.-India Collaborative Research: Low-Temperature Studies of Hall Effect and Specific Heat in Amorphous Alloys, Award in U.S. and Indian Curreny

描述：这是一个美国-印度在凝聚态物理/材料科学方面的研究合作项目，由德克萨斯州a&m研究基金会的Donald Naugle和坎普尔印度理工学院的A.K. Majumdar指导。这项名为“非晶合金中霍尔效应和比热的低温研究”的拟议研究将确定金属玻璃的电学和磁性能之间的相关性。虽然在顺磁性玻璃金属的电输运编目和解释方面取得了相当大的进展，但非磁性过程以及与磁性和磁散射过程相关的非磁性过程在非晶磁性合金中的相对重要性尚未完全确立。美国小组在研究非磁性非晶合金的电子传递和表面化学方面一直是最活跃的，而印度小组在研究磁性玻璃金属的电子传递方面一直是一个主要因素。两个小组的专业知识和实验能力具有很强的互补性，可以很好地结合起来完成研究目标。范围：在美国，对非晶金属的研究一度远比印度密集。然而，美国的研究重点已经转移到其他领域。目前，没有一个研究项目是专门为非晶态金属的研究而资助的。在印度乃至全世界，这个主题的主要工作将由Majumdar和他在坎普尔的团队来完成。美国的合作将确保获得非晶金属的主要实验研究，以低成本获得由此产生的技术，并进一步了解非晶合金的基本运输。＊＊＊

9603137 Naugle Description: This is a U.S.-India research collaboration in condensed matter physics/materials science under the direction of Donald Naugle, Texas A&M Research Foundation and A.K. Majumdar, Indian Institute of Technology, Kanpur. The proposed research entitled Low Temperature Studies of Hall Effect and Specific Heat in Amorphous Alloys will determine the correlations between the electrical and magnetic properties of metallic glasses. While considerable progress has been made in cataloging and explaining electrical transport in paramagnetic glassy metals, the relative importance of nonmagnetic processes and those associated with magnetism and magnetic scattering processes in amorphous magnetic alloys has not been completely established. The U.S. group has been among the most active studying electron transport and surface chemistry of nonmagnetic amorphous alloys, and the Indian group has been a major factor in the study of electron transport in magnetic glassy metals. The expertise and experimental capabilities of the two groups are highly complementary and will combine well to accomplish the research objectives. Scope: In the United States the study of amorphous metals had, at one time, been far more intensive than in India. However, research priorities in the United States have shifted to other areas. Presently, no research programs are funded solely for the study of amorphous metals. The main effort on this topic in India and perhaps worldwide will be performed by Majumdar and his group at Kanpur. U.S. collaboration will insure access to major experimental research on amorphous metals, access to the resulting technology at low cost, and the furthering of basic understanding on transport in amorphous alloys. ***
