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.

技术总结：量子设计物理性能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多功能的工具。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磁性材料和器件。这种多功能仪器将允许测量电子输运，自旋输运和磁性材料，以及地形和磁成像在广泛的温度和磁场（高达14特斯拉）。 这个强大的和广泛适用的工具，目前还没有提供给俄勒冈州立大学的材料研究界在大，将使和加速广泛的材料研究课题。 特别是，它旨在解决OSU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研究人员提供从单个磁性结构到新型散装材料的探测系统的关键能力。它将安装在现有的俄勒冈州立大学用户设施，以保证长期的仪器维护和保养，并确保访问该仪器由中央俄亥俄州的广泛的学术和商业材料社区。该仪器将扩大覆盖面，并加强对本科生和研究生的尖端材料研究教育。简单总结：具有新颖特性的新材料是提高商业企业生产力和改善生活质量的技术。新功能的发现严重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。 这样做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。 我们建议购买这样一个强大的工具，一个高场物理特性测量系统与低温AFM/MFM，这有助于我们了解各种材料。该仪器目前在俄亥俄州中部的材料研究界尚不可用。该仪器将驻留在现有的OSU用户设施中，对大学和工业用户开放。除了确保广泛的研究人员访问，将其定位在我们的设施将保证这一强大的仪器保持在最佳状态的专业人士，以最大限度地提高科学和公共回报，这项研究基础设施的投资。 该工具将特别有利于最近NSF资助的材料研究科学与工程中心，该中心专注于在技术上重要的材料中实现新的磁性功能。 该仪器的自动化性质使其可供本科生和研究生使用，从而提高了我们明天的教学能力。的科学领导人如何进行尖端材料研究。
