Acquisition of a SQUID Magnetometer

该提案要求提供资金，为克拉克大学化学和凝聚态物理学的材料研究提供现代化的多功能磁性仪器。 磁力计将作为新一代基于分子的量子反铁磁体的合成和表征计划的中心仪器。研究一直集中在基于分子的磁性，最近集中在低维量子反铁磁体的设计和合成，具有显着的重叠与高温超导的磁性。这一新仪器将有助于满足物理组和合成化学组的互补要求。一个多产的，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。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。所要求的磁强计也将是研究人员的主力仪器，他们需要对最有趣的新材料的磁化强度和直流和可磁化性的场和温度依赖性进行广泛的研究。我们的学生，本科生和研究生，从这个研究项目的多学科性质的利润。当学生看到他们自己的工作放在一个更广泛的科学背景下，他们开发其他学科的赞赏。由于化学和物理实验室在同一栋大楼内，每天都有互动的机会，这是良好协作的最佳选择。新仪器的可用性将对我们可以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，而不是与不合适的仪器作斗争。化学家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。这种参与的增加将使他们更加独立，减少周转时间，提高生产力。

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.
