A Materials Characterization Instrument for Condensed Matter Physics Laboratories

9451949 Cunningham认识到凝聚态物理在本科科学教育中的重要性，格林内尔学院寻求获得一种变温度、高磁场材料表征仪器，用于将凝聚态物理实验整合到物理课程中。为了与格林内尔在教学和实践经验方面的创新保持一致，物理系设想了一种高度灵活的仪器，可用于测量各种样品的电阻率，直流磁化率和交流磁化率。该仪器将通过霍尔效应、量子霍尔效应、德哈斯-范阿尔芬效应、居里定律和超导体临界磁场等五项新的凝聚态实验，增强中高级实验室的能力。这些新的实验将丰富学生在凝聚态物理方面的经验，使他们能够在实验室中探索他们目前只在教科书中遇到的现象。通过实验体验，学生将探索一般概念，观察重要的物理现象，并学习低温和凝聚态物理的实验技术。此外，提议的仪器将使高级学生能够在凝聚态物理方面做独立的项目和暑期研究。

9451949 Cunningham Recognizing the importance of condensed matter physics in undergraduate science education, Grinnell College seeks to acquire a variable temperature, high-magnetic field materials characterization instrument that will be used to integrate condensed matter physics experiments into the physics curriculum. In keeping with Grinnell's emphasis on innovation in teaching and practical experience for students, the physics department envisions a highly flexible instrument which can be used to measure the resistivity, the dc magnetization, and the ac magnetic susceptibility of a variety of samples. The proposed instrument will enhance the intermediate and advanced laboratories with five new condensed matter experiments: the Hall effect, the quantum Hall effect, the de Haas-van Alphen effect, Curie's law, and the critical magnetic field of superconductors. These new experiments will enrich the experience of students in condensed matter physics by allowing them to explore in the laboratory phenomena which they currently encounter only in textbooks. Through this laboratory experience, students will explore general concepts, observe important physical phenomena, and learn experimental techniques in low-temperature and condensed matter physics. In addition, the proposed instrument will enable advanced students to do independent projects and summer research in condensed matter physics.
