MRI: Acquisition of High Field Physical Properties Measurement System with Cryogenic AFM/MFM

技术概述：Quantum Design物理性质测量系统与兼容的低温原子力/磁力扫描探针显微镜(AFM/MFM)相结合，将为俄亥俄州中部的材料研究社区提供一个强大而通用的工具。通过在纳米尺度上定制多组分材料的结构和组成，正在创造具有前所未有的能力和性能水平的新的磁性材料和装置。这种多功能仪器将允许测量此类材料的电子输运、自旋输运和磁性，以及在广泛的温度和磁场范围内(高达14特斯拉)进行地形和磁性成像。这一功能强大且适用范围广泛的工具目前尚未为俄亥俄州立大学材料研究界所用，它将支持并加速广泛的材料研究课题。特别是，它的设计是为了应对俄亥俄州立大学新获得的NSF资助的材料研究科学与工程中心(MRSEC)所面临的挑战，该中心正在研究磁电子学中的两个主题：自旋保持网络和复杂氧化物异质结构。该仪器将为MRSEC研究人员提供关键能力，以探测从单个磁结构到新型块状材料的各种系统。它将安装在俄亥俄州州立大学现有的用户设施中，以保证仪器的长期维护和维护，并确保俄亥俄州中部广大的学术和商业材料社区能够使用该仪器。该仪器将扩大范围，加强本科生和研究生在尖端材料研究方面的教育。莱曼总结：具有新特性的新材料使技术成为可能，从而提高商业企业的生产率和生活质量。新功能的发现在很大程度上依赖于告诉我们这些新的、通常是微小的材料和设备如何工作的工具。完成这项工作所需的仪器越来越复杂和昂贵，使它们超出了大多数研究人员的能力范围。我们打算购买这样一个强大的工具，一个具有低温AFM/MFM的高场物理性质测量系统，它可以帮助我们理解各种材料。目前，俄亥俄州中部的材料研究社区普遍无法使用这种仪器。该仪器将存放在俄亥俄州立大学现有的用户设施中，对大学和工业用户开放。除了确保研究人员的广泛接触外，将其放置在我们的设施中还将确保这一强大的仪器由专业人员保持在最佳状态，以最大限度地提高这一研究基础设施投资的科学和公共回报。这一工具将特别有利于最近由美国国家科学基金会资助的材料研究科学和工程中心，该中心专注于在具有重要技术价值的材料中实现新的磁性功能。仪器的自动化特性使本科生和研究生都能接触到它，从而增强了我们明天教授科学领袖S如何进行尖端材料研究的能力。

Technical Summary: The Quantum Design Physical Properties Measurement System combined with a compatible cryogenic Atomic Force/Magnetic Force scanning probe Microscope (AFM/MFM) will provide a powerful and versatile tool to central Ohio's materials research community. New magnetic materials and devices with unprecedented capabilities and levels of performance are being created by tailoring the structure and composition of multi-component materials at the nanometer scale. This versatile instrument will allow measurements of electronic transport, spin transport and magnetic properties of such materials as well as topographic and magnetic imaging over a wide range of temperatures and magnetic fields (up to 14 Tesla). This powerful and broadly applicable tool, not currently available to the OSU materials research community at large, will enable and accelerate a broad spectrum of materials research topics. In particular it is designed to address challenges faced by OSU's newly awarded NSF-funded Materials Research Science and Engineering Center (MRSEC) which is studying two topics in magnetoelectronics: Spin-Preserving Networks and Complex Oxide Heterostructures. The instrument will provide MRSEC researchers with the critical ability to probe systems ranging from individual magnetic structures to novel bulk materials. It will be installed in an existing OSU user facility to guarantee long-term instrument maintenance and upkeep and to ensure access to the instrument by the central Ohio's broad academic and commercial materials community. The instrument will broaden outreach and enhance the education of undergraduate and graduate students in cutting edge materials research.Layman's Summary: New materials with novel properties are enabling technologies that enhance the productivity of commercial enterprises and improve quality of life. The discovery of new capabilities is critically dependent on the tools that tell us how these new, often tiny, materials and devices work. The instruments needed to do this are increasingly sophisticated and expensive, putting them beyond the reach of most researchers. We propose to purchase such a powerful tool, a High Field Physical Properties Measurement System with Cryogenic AFM/MFM, that helps us understand a variety of materials. This instrument is not currently available to the materials research community, at large, in central Ohio. The instrument will reside in an existing OSU user facility open to both university and industrial users. In addition to ensuring broad researcher access, locating it in our facility will guarantee that this powerful instrument is kept in top condition by professionals to maximize scientific and public returns on this research infrastructure investment. This tool will particularly benefit a recently NSF funded Materials Research Science and Engineering Center that is focused on enabling new magnetic functionalities in technologically important materials. The automated nature of the instrument makes it accessible to undergraduate and graduate students and so enhances our ability to teach tomorrow?s scientific leaders how cutting edge materials research is done.
