Acquisition of a SQUID Magnetometer

这项提案要求提供资金，为克拉克大学化学和凝聚态物理的材料研究提供现代、多功能的磁性仪器。磁力计将作为新一代分子基量子反铁磁体合成和表征计划的中心仪器。基于分子的磁性一直是研究的重点，最近集中在设计和合成与高温超导磁性有显著重叠的低维量子反铁磁体。这台新仪器将有助于满足物理组和合成化学组的互补要求。一种高效、多功能的磁力计已成为合成磁化学家不可或缺的分析工具。对一种新化合物的初步批次测量可以为确定一种新化合物的必要合成途径提供指导。所要求的磁强计也将是研究人员的主要工具，他们需要广泛地研究磁场和温度对磁化的依赖关系，以及对最有趣的新材料的直流和交流磁化率的研究。我们的学生，包括本科生和研究生，都从这项研究项目的多学科性质中受益。当学生看到自己的工作被放在更广泛的科学背景下时，他们会对其他学科产生欣赏。由于化学和物理实验室在同一栋建筑内，每天都有互动的机会，这是良好协作的最佳选择。新仪器的推出将对我们为学生提供的教育机会产生重大影响。对于化学和物理专业的学生来说，新的磁力计将使他们能够专注于科学，而不是努力解决仪器不足的问题。化学家们将能够利用新磁力计的用户友好界面来运行他们自己的样品。这种更多的参与将使他们更加独立，减少周转时间并提高他们的生产率。

This proposal requests funds to provide modern, versatile magnetic instrumentation for materials research in chemistry and condensed matter physics at Clark University. A magnetometer will serve as the central instrument of a program in the synthesis and characterization of a new generation of molecular-based quantum antiferromagnets. Research has been focused on molecular-based magnetism, concentrating recently on the design and synthesis of low-dimensional quantum antiferromagnets that have significant overlap with the magnetism of high-temperature superconductivity. This new instrument will help meet the complementary requirements of the physics group and the synthetic chemistry group. A productive, versatile magnetometer has become an indispensable analytical tool for synthetic magnetochemists. Measurements of a preliminary batch of a new compound can provide guidance for determining the necessary synthetic pathway to a new compound. The requested magnetometer will also be the workhorse instrument for the researchers who need to make extensive studies of the field and temperature dependences of the magnetization and dc-and ac-susceptibilities studies of the most interesting of the new materials. Our students, both undergraduate and graduate, profit from the multidisciplinary nature of this research project. When students see their own work placed within a broader scientific context they develop an appreciation for other disciplines. Because the chemistry and physics laboratories are within the same building, opportunities for interaction occur daily, optimal for good collaborative work. The availability of the new instrument will have a strong impact on the educational opportunities we can offer our students. For both chemistry and physics students, the new magnetometer will allow them to concentrate on the science, and less on struggling with inadequate instruments. The chemists will be able to take advantage of the user-friendly interface of the new magnetometer to run their own samples. This increased involvement will render them more independent, decreasing the turnaround time and increasing their productivity.
