Acquisition of a SQUID Magnetometer

本提案要求资金为克拉克大学化学和凝聚态物理材料研究提供现代、通用的磁性仪器。磁力计将作为新一代分子基量子反铁磁体合成和表征程序的中心仪器。研究主要集中在基于分子的磁性上，最近集中在设计和合成低维量子反铁磁体上，这些磁体与高温超导的磁性有很大的重叠。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。高效、通用的磁强计已成为合成磁化学家不可或缺的分析工具。新化合物的初步批次的测量可以为确定新化合物的必要合成途径提供指导。所要求的磁力计也将成为研究人员的主要仪器，他们需要对最有趣的新材料的磁场和温度依赖性进行广泛的研究，并对直流和交流磁化率进行研究。我们的学生，无论是本科生还是研究生，都从这个研究项目的多学科性质中受益。当学生看到自己的工作被置于更广阔的科学背景中时，他们会对其他学科产生欣赏。因为化学和物理实验室在同一栋楼里，所以每天都有互动的机会，这对于良好的协作工作是最理想的。新仪器的可用性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，新的磁力计可以让他们把精力集中在科学上，而不是在仪器不足的情况下苦苦挣扎。化学家们将能够利用新型磁力计的用户友好界面来运行他们自己的样品。这种增加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力。

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.
