9703732 Schiffer This award provides partial support for a SQUID magnetometer to be located on the campus of the University of Notre Dame, where no equivalent device currently exists. Such a magnetometer can measure the magnetization of samples as a function of temperature and magnetic field. The proposed instrument is extremely sensitive and therefore is appropriate for measuring both bulk and thin film samples. Its operation is almost completely computer-controlled, so that it is capable of a high throughput of samples, and the operating costs are rather low. Several research groups at Notre Dame and one at Western Michigan University will be the primary users of this magnetometer. In each case, the measurement capabilities of the magnetometer will greatly enhance currently existing research and make new experiments possible. The research areas are quite diverse, including: Intermetallic cluster compounds, high temperature superconductivity, metalloporphyrim chemistry, colossal magnetoresistance materials, geometrically frustrated magnets, and diluted magnetic semiconductors (including thin films and superlattices). This instrument will truly be used in an interdisciplinary fashion since the above research involves groups in three different departments. Several other research groups on the Notre Dame campus also have occasional use for such a magnetometer and will be given access. %%% This award provides partial support for a SQUID magnetometer to be located on the campus of the University of Notre Dame, where no equivalent device currently exists.

9703732 Schiffer该奖项为安装在圣母大学校园内的SQUID磁强计提供部分支持，目前圣母大学还没有类似的设备。这种磁强计可以测量样品的磁化强度作为温度和磁场的函数。该仪器灵敏度极高，适用于块状和薄膜样品的测量。它的操作几乎完全由计算机控制，因此它能够高通量地处理样品，并且操作成本相当低。巴黎圣母院的几个研究小组和西密歇根大学的一个研究小组将是这种磁力仪的主要用户。在每一种情况下，磁力计的测量能力都将极大地增强当前的研究，并使新的实验成为可能。研究领域相当广泛，包括：金属间簇合物、高温超导、金属卟啉化学、巨磁电阻材料、几何受阻磁体和稀磁半导体(包括薄膜和超晶格)。由于上述研究涉及三个不同部门的小组，因此这一工具将真正以跨学科的方式使用。巴黎圣母院校区的其他几个研究小组也偶尔会使用这样的磁力计，并将允许使用。%此奖项为安装在圣母大学校园内的SQUID磁强计提供部分支持，目前圣母大学校园内还没有类似的设备。这种磁强计可以测量样品的磁化强度作为温度和磁场的函数。该仪器灵敏度极高，适用于块状和薄膜样品的测量。它的操作几乎完全由计算机控制，因此它能够高通量地处理样品，并且操作成本相当低。巴黎圣母院的几个研究小组和西密歇根大学的一个研究小组将是该磁力仪的主要用户。在每一种情况下，磁力计的测量能力都将极大地增强当前的研究，并使新的实验成为可能。研究领域相当广泛，包括：金属间簇合物、高温超导、金属卟啉化学、巨磁电阻材料、几何受阻磁体和稀磁半导体(包括薄膜和超晶格)。由于上述研究涉及三个不同部门的小组，因此这一工具将真正以跨学科的方式使用。巴黎圣母院校区的其他几个研究小组也偶尔会使用这样的磁力计，并将允许使用。***
