9875193MolerThis CAREER project will focus on improved measurements of magnetic field distributions on small length scales. 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.***

9875193MolerThis CAREER项目将专注于改进小长度尺度上磁场分布的测量。它将导致超导和磁性材料的进步，这些材料具有自然发生的磁性结构，以及人工结构的介观材料。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）、霍尔探针和超导量子干涉器件（SQUID）各自具有特定的优点和缺点。 这些传感器的制造，测试和后续实验将为材料物理和纳米纤维技术的研究生和本科生提供培训。 该奖项还将部分支持基于微制造的研究经验课程的开发，该课程将为本科生提供微制造的科学原理和实践的坚实基础，并有机会构思，设计，制造和表征自己的微制造设备。 本课程将作为新的应用物理辅修课程的一部分提供，适用于工程和科学专业的本科生，该课程由历史上毕业的斯坦福大学应用物理系提供。该项目的重点是与小尺度电子结构研究相关的纳米制造磁传感器领域的研究。 此外，该项目将部分支持开发一个新的基于微加工的研究课程，为本科生提供微加工的科学原理和实践的坚实基础，并有机会构思，设计，制造和表征自己的微加工设备。 本课程是斯坦福大学应用物理系新开设的应用物理本科辅修课程的一部分。本提案支持的工作将在斯坦福大学纳米纤维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纤维技术方面的培训。
