9971827SchmiedeshoffIn this research, conducted in an undergraduate institution, the relationship between superconductivity and magnetism will be explored in the nickel boride family of materials. The overall goal is to identify and characterize the ground states of these materials. Specifically, a dilatometer will be used to measure the thermal expansion and magnetostriction of the magnetic material YBNi2B2C and the non-magnetic superconductor LuNi2B2C. A comparison of the resulting measurements for these two materials allows the separation of the magnetic component of the Yb compound. Furthermore, undergraduate students will participate in this research. Most of the work will be done on the campus of Occidental College, with the remainder at the National High Magnetic Field Laboratory. The undergraduate students will fully engage in this project and gain first hand experience to do research and interact with scientists in a major research environment.%%%This research project will be conducted with undergraduate students at Occidental College and at the National High Magnetic Field Laboratory. The research focuses on the experimental determination of certain magnetic and superconducting properties of two members of a family of nickel-boron compounds. The results will contribute to the understanding of superconductivity. Moreover, this project has a very strong educational component. The undergraduate participants will gain experience in one of the current forefront areas of condensed matter physics. In addition to their work done at Occidental College their presence at the National High Magnetic Field Laboratory will give them experience in research conducted in a major research environment, where they will interact with experienced scientists as research colleagues.

[9971827] schmiedeshoff在一所本科院校进行的这项研究中，将探讨硼化镍族材料的超导性和磁性之间的关系。总体目标是识别和表征这些材料的基态。具体来说，将使用膨胀计来测量磁性材料YBNi2B2C和非磁性超导体LuNi2B2C的热膨胀和磁致伸缩。对这两种材料的测量结果进行比较，可以分离出Yb化合物的磁性成分。此外，本研究将由本科生参与。大部分工作将在西方学院校园内完成，其余工作将在国家强磁场实验室完成。本科生将充分参与该项目，并获得在主要研究环境中进行研究和与科学家互动的第一手经验。本研究项目将由美国西方学院的本科生和美国国家强磁场实验室共同完成。本研究的重点是镍硼化合物家族中两个成员的某些磁性和超导性的实验测定。这些结果将有助于对超导性的理解。此外，这个项目有很强的教育成分。本科参与者将获得凝聚态物理当前前沿领域之一的经验。除了他们在西方学院完成的工作外，他们在国家强磁场实验室的存在将使他们获得在主要研究环境中进行研究的经验，在那里他们将与经验丰富的科学家作为研究同事进行互动。
