This grant supports the acquisition of a Scanning Hall Probe Microscope (SHPM) system, for the quantitative, noninvasive measurement of surface magnetic fields at the nanometer length scale. This recently developed robust instrument is a low temperature/room temperature SHPM that can be operated simultaneously in either the SHPM and STM modes or the SHPM and AFM modes to provide complementary information. This instrument is ideally suited for the study of magnetic nano/micro structures: 1) it can operate in high magnetic fields (easily to above 7 Tesla); 2) it has high field and spatial resolution (about 50 nanometers); 3) it does not require automatically smooth, oxide free surfaces. It will consist of a room temperature head for use with larger samples, a low temperature head with superconducting solenoid for operation in the temperature range 1.5-300 K at fields up to 8 Tesla, and one controller to operate the two heads. The room temperature head will handle much larger samples and can be operated in air or a controlled atmosphere. This configuration is well suited for training personnel in the SHPM techniques. This project will support research on nanomagnets and magnetic nano/microstructures at Texas A&M University including the study of nanomagnets, single magnetic molecules, hybrid magnetic devices and magnetic traps to manipulate biological specimens. There is an active interdisciplinary materials research program at Texas A&M University. Approximately 40 students (undergraduate, graduate and postdoctoral) with the principle users will benefit in their research in the design of new Single Molecule Magnets (SMMs), thin films and composite materials of SMM's. In addition to providing new research capability, this instrument serves to train postdoctoral students, graduate students, undergraduate students and high school teachers and their students in the fundamental principles of nanomagnets and scanning probe microscopies. Approximately 20% of the instrument operating time will be dedicated to education and training. Students having access to this instrument will learn about magnetic fields and magnetic nanostructures. The instrument will be integrated into the interdisciplinary materials science graduate laboratory course, and special research projects for undergraduates and gifted high school students. In particular, a large number of University Honors Fellows (advanced undergraduates undertaking an Honors research thesis) and NASA Sharp participants (gifted minority high school students) will benefit from having access to this opportunity over the lifetime of the instrument.

该补助金支持收购扫描霍尔探针显微镜（SHPM）系统，用于纳米长度尺度的表面磁场的定量，非侵入性测量。 这种最近开发的强大的仪器是一个低温/室温SHPM，可以同时在SHPM和STM模式或SHPM和AFM模式，以提供互补的信息。该仪器非常适合磁性纳米/微米结构的研究：1）它可以在高磁场中工作（很容易达到7特斯拉以上）; 2）它具有高的场和空间分辨率（约50纳米）; 3）它不需要自动平滑，无氧化物表面。 它将包括一个用于较大样品的室温头，一个带有超导螺线管的低温头，用于在1.5-300 K的温度范围内在高达8特斯拉的磁场下工作，以及一个控制器来操作两个头。 室温头将处理更大的样品，可以在空气或受控气氛中操作。 这种配置非常适合于培训SHPM技术的人员。 该项目将支持德克萨斯A M大学的纳米磁体和磁性纳米/微观结构研究，包括纳米磁体，单磁性分子，混合磁性器件和磁性陷阱的研究，以操纵生物标本。 德克萨斯A M大学有一个活跃的跨学科材料研究项目。大约40名学生（本科生，研究生和博士后）与主要用户将受益于他们的研究，在新的单分子磁体（SMM），薄膜和复合材料的SMM的设计。 除了提供新的研究能力外，该仪器还用于培训博士后学生，研究生，本科生和高中教师及其学生掌握纳米磁体和扫描探针显微镜的基本原理。 大约20%的仪器操作时间将用于教育和培训。 有机会使用该仪器的学生将了解磁场和磁性纳米结构。 该仪器将被整合到跨学科材料科学研究生实验室课程，以及本科生和天才高中生的特殊研究项目中。 特别是，大量的大学荣誉研究员（高级本科生进行荣誉研究论文）和NASA夏普参与者（有天赋的少数民族高中生）将受益于在仪器的生命周期内获得这个机会。
