中文摘要
这个项目是对超低温材料的研究和超低温技术的发展。实验是在远低于1K的温度下进行的。介绍了几个领域的研究。一个是超流体3He的磁性。这些实验之所以有趣,是因为它们将为现有理论提供重要的检验,并解决与低温磁测量方法相关的基本问题。二是3He薄膜的磁性。薄膜磁性与3He的体磁性有一些有趣的不同。第三个领域是金属薄膜的输运特性和基于超导量子干涉器件(squid)的仪器的发展。这包括介观物理学新领域的重要研究。各种各样的研究项目都是基础性的,但在低温下操作的先进材料和设备的背景下可能具有技术相关性。例如,超灵敏的SQUID装置已用于临床研究源自脑电波活动的弱磁场。这个项目是对超低温材料的研究和超低温技术的发展。实验是在远低于1K的温度下进行的。介绍了几个领域的研究。一个是超流体3He的磁性。这些实验之所以有趣,是因为它们将为现有理论提供重要的检验,并解决与低温磁测量方法相关的基本问题。二是3He薄膜的磁性。薄膜磁性与3He的体磁性有一些有趣的不同。第三个领域是金属薄膜的输运特性和基于超导量子干涉器件(squid)的仪器的发展。这包括介观物理学新领域的重要研究。各种各样的研究项目都是基础性的,但在低温下操作的先进材料和设备的背景下可能具有技术相关性。例如,超灵敏的SQUID装置已用于临床研究源自脑电波活动的弱磁场。
英文摘要
9501209 Bozler This project is a study of materials at ultralow temperatures and the development of ultralow temperature techniques. The experiments are carried out at temperature substantially below 1K. Several areas research are represented. One addresses the magnetic properties of superfluid 3He. The experiments are of interest because they will provide important test of extant theories, and address fundamental issues related to low temperature magnetic measurement methods. The second is the magnetism of thin films of 3He. The thin film magnetism differs in interesting ways from bulk magnetic properties of 3He. The third area is the transport properties of thin metal films and the development of instrumentation based on superconducting quantum interference devices (SQUIDS). This includes important research in a new area of mesoscopic physics. The various research projects are of a fundamental nature, but may have technical relevance in the context of advanced materials and devices operating at cryogenic temperatures. For example, ultrasensitive SQUID devices have been employed in clinical studies of the weak magnetic fields originating from brain wave activity. %%% This project is a study of materials at ultralow temperatures and the development of ultralow temperature techniques.
