Acquisition of Vibrating Sample Magnetometer for Magnetic Materials Research and Education

该补助金用于资助布法罗纽约州立大学购置一台振动样品磁强计（VSM），用于磁性材料的研究和教育。VSM设备是完全集成和自动化的，具有高灵敏度。目前的研究项目利用新设备涵盖了广泛的磁性材料：巨磁电阻自旋阀，交换各向异性薄膜，磁光多层膜，巨磁致伸缩薄膜和多层膜，磁性形状记忆合金块，薄膜和多层膜，以及弹道磁电阻材料。这些项目是从磁性，自旋相关的电子输运和自旋电子学的物理学的观点的根本利益。 对这些材料的研究在超高密度数据存储器件、磁传感器、光存储系统和微系统换能器等领域具有广泛的技术应用。 该仪器将加强该大学在纳米科学和纳米技术方面的广泛目标。该基本工具在该大学用于材料的常规磁性表征的可用性将为研究以及学生培训，教育和推广活动提供机会。新的VSM还将加强合作研究。 教师积极参与学生培训，教育和推广活动，少数民族和妇女的参与。继续和扩大以前的活动，目前的努力涉及研究生，本科生和高中学生的动手培训。外展活动包括为布法罗地区内城区高中的少数族裔和女学生（通常为14-18岁）提供为期五周的夏季学徒计划，以及为本科生提供实验室体验。 参与的学生将受益于VSM通过学习使用和理解材料的磁性行为。此外，来自纽约州立大学布法罗分校的其他从事磁性材料研究和教育的研究人员将有机会使用新设备。

This grant supports the acquisition of a vibrating sample magnetometer (VSM) for magnetic materials research and education at SUNY at Buffalo. The VSM equipment is fully integrated and automated with high sensitivity. Current research projects making use of the new equipment cover a broad range of magnetic materials: giant magnetoresistance spin valves, exchange anisotropy films, magneto-optical multilayers, giant magnetostriction thin films and multilayers, magnetic shape memory alloy bulk, thin films, and multilayers, and materials for ballistic magnetoresistance. These projects are of fundamental interest from the viewpoint of the physics of magnetism, spin dependent electron transport and spintronics. Research on these materials has broad technological applications in the areas of ultra-high density data storage devices, magnetic sensors, optical storage systems, and transducers for microsystems. This instrument will enhance the broad goals of the university in nanoscience and nanotechnology.The availability of this basic tool for routine magnetic characterization of materials at the university will provide opportunities for research and also student training, education, and outreach activities. The new VSM will also enhance collaborative research. Faculty are active in student training, education, and outreach activities, with the involvement of minorities and women. Continuing and expanding upon previous activities, current efforts involve hands-on training for graduate, undergraduate, and high school students. Outreach activities include a five-week summer apprentice program for minorities and women students (typically 14-18) from Buffalo-area inner city high schools, and laboratory experience for undergraduates. Participating students will benefit from the VSM by learning to use and understand the magnetic behavior of materials. In addition, other researchers from SUNY-Buffalo pursuing research and education in magnetic materials will have access to the use of the new equipment.
