CAREER: Nanofabrication of Local Magnetic Sensors for Materials Physics

这个职业项目将专注于改进小长度尺度上的磁场分布测量。它将导致具有自然磁性结构的超导和磁性材料以及人工构造的介观材料的进步。该项目的主要目标是开发具有足够灵敏度的传感器，通过检测持续电流产生的磁场来成像介观电子现象。磁力显微镜(MFM)、霍尔探测器和超导量子干涉器件(SQUID)各有其优缺点。这些传感器的制造、测试和后续实验将为研究生和本科生提供材料物理和纳米制造技术方面的培训。该奖项还将部分支持基于微制造的研究体验课程的开发，该课程将为本科生提供微制造科学原理和实践的坚实基础，并有机会构思、设计、制造和表征他们自己的微制造设备。这门课程将作为新的应用物理辅修课程的一部分，面向工程和科学专业的本科学生，该辅修课程由历史上毕业的斯坦福大学应用物理系提供。%本项目专注于与小长度尺度上的电子结构研究相关的纳米级磁性传感器领域的研究。此外，该项目将部分支持开发一门新的基于微细加工的研究课程，为本科生提供微细加工科学原理和实践的坚实基础，并有机会构思、设计、制造和表征他们自己的微细加工设备。这门课程将是斯坦福大学应用物理系新开设的应用物理学本科辅修课程的一部分，该系历来只是一个研究生系。这项提议支持的工作将在斯坦福纳米制造设施和新建的先进材料实验室为研究生和本科生提供材料研究和纳米制造技术方面的培训。*

It will lead to advances in superconducting and magnetic materials, which have naturally occurring magnetic structure, and in artificially structured mesoscopic materials. The major goal of this project is the development of sensors with sufficient sensitivity to image mesoscopic electronic phenomena by detecting the magnetic fields produced by persistent currents. Magnetic Force Microscopes (MFMs), Hall probes, and Superconducting QUantum Interference Devices (SQUIDs) each have particular advantages and disadvantages. Fabrication, testing, and subsequent experimentation with these sensors will provide training for graduate and undergraduate students in materials physics and nanofabrication techniques. This award will also partially support the development of a microfabrication-based research experience course, which will provide undergraduates with a solid grounding in the scientific principles and practice of microfabrication, and with the opportunity to conceive, design, fabricate, and characterize their own microfabricated device. This course will be offered as part of a new applied physics minor, intended for undergraduate engineering and science majors, which is being offered by the historically graduate Stanford Applied Physics Department.%%%This project focuses on research in the area of nanofabricated magnetic sensors related to the study of electronic structure on small length scales. In addition, the project will partially support the development of a new microfabrication-based research course to provide undergraduates with a solid grounding in the scientific principles and practice of microfabrication, and with the opportunity to conceive, design, fabricate, and characterize their own microfabricated device. This course will be part of a new undergraduate minor in applied physics being introduced by the Stanford Applied Physics Department which has historically been solely a graduate department. The work supported under this proposal will provide training for both graduate and undergraduate students in materials research and nanofabrication techniques at the Stanford Nanofabrication Facility and at the newly constructed Laboratory for Advanced Materials.***
