With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at North Carolina State University will acquire a a Superconducting Quantum Interface Device (SQUID) magnetometer. This equipment will enable researchers to carry out studies on a) synthesis and characterization of open-shell molecules and materials; b) crystalline and liquid crystalline metal halides; c) magnetic susceptibility in metalloproteins; and d) development of novel contrast agents for magnetic resonance imaging. A SQUID magnetometer is critical for studying the magnetic properties of materials, particularly for weakly magnetic/small moment samples. In a DC magnetization measurement, one measures the magnetic moment as a function of applied DC magnetic field (and/or temperature). Using DC magnetization experiments, one can determine magnetic moments or a hysteresis curve, or identify magnetic phase transitions. In such a fashion, complete magnetic characterization of single crystal samples and films is possible. These types of measurements are essential in order to understand polymers and thin films.

通过化学研究工具和设施（CRIF）计划的奖项，北卡罗来纳州立大学化学系将获得超导量子接口设备（Squid）磁力计。该设备将使研究人员能够进行有关a）开放壳分子和材料的合成和表征的研究； b）结晶和液晶金属卤化物； c）金属蛋白中的磁敏感性； d）开发用于磁共振成像的新型对比剂。 鱿鱼磁力计对于研究材料的磁性特性至关重要，尤其是对于弱磁/小矩样品。 在DC磁化测量中，一个人测量了磁矩与所施加的直流磁场（和/或温度）的函数。 使用DC磁化实验，可以确定磁矩或磁滞曲线或识别磁相变。 以这种方式，可以对单晶样品和膜进行完全的磁性表征。 这些类型的测量对于了解聚合物和薄膜至关重要。
