IMR-MIP: High Spatial Resolution Sampling Scanning SQUID Microscope

材料研究部的这一奖项支持斯坦福大学的概念工程设计和原型扫描采样超导量子干涉装置(SQUID)显微镜的开发。高空间分辨率采样扫描鱿鱼显微镜是世界上最灵敏的磁探测器之一？S。该项目将为科学家和工程师提供一种具有纳米级空间分辨率和单电子自旋灵敏度的时间无关磁场的新成像能力。它将能够以10皮秒的时间分辨率对随时间变化的磁场进行成像。这种对纳米磁性现象的测量在信息技术、生物技术、能源技术以及基础科学中都很有意义。该显微镜旨在成为两个共址共享用户设施的通用用户工具，这两个设施是斯坦福纳米加工设施(SNF)，国家纳米加工基础设施网络的成员，以及纳米尺度探测中心(CPN)。在用户、科学家和工程师手中，显微镜将成为一种变革性的工具，需要表征各种不同的材料，如超导体、磁性纳米粒子、磁性半导体和多铁性。该项目是基于IBM和斯坦福大学之间的合作。这种大学和行业的合作将允许在工业环境中为不同的学生和博士后群体提供指导和实践经验。

This award from the Division of Materials Research supports Stanford University with the conceptual engineering design and development of a prototype scanning sampling Superconducting Quantum Interference Device (SQUID) microscope. High spatial resolution sampling scanning SQUID microscopes are among the world?s most sensitive magnetic detectors. The project will provide scientist and engineers with a new imaging capability of time-independent magnetic fields with nanoscale spatial resolution and single electron spin sensitivity. It will enable imaging of time-dependent magnetic fields with 10 picoseconds time resolution. Such measurements of nanomagnetic phenomena are of interest in information technology, biotechnology, and energy technology, as well as fundamental science. The microscope is designed to become a general user tool at two co-located shared user facilities, the Stanford Nanofabrication Facility (SNF), a member of the National Nanofabrication Infrastructure Network, and the Center for Probing the Nanoscale (CPN). The microscope would be a transformative tool in the hands of the users, scientists and engineers, needing to characterize such widely varying materials as superconductors, magnetic nanoparticles, magnetic semiconductors, and multiferroics. The project is based on collaboration between IBM and Stanford. This university-industry collaboration will allow mentoring and hands-on experience for a diverse group of students and postdocs in an industrial environment.
