MRI: Acquisition of a Magnetic Property Measurement System for Nanotechnology and Materials Science Research at the University of Puerto Rico at Mayaguez

通过这笔赠款，波多黎各大学，马亚圭斯将获得一个磁性能测量系统，将支持纳米技术和材料科学与工程的研究和教育工作。该系统基于超导干涉装置，将允许准确测定磁粉和薄膜以及块状材料的直流磁特性（包括磁各向异性）。该设备将允许表征新型磁活性材料，如磁性纳米颗粒悬浮液和粉末，软和硬铁氧体，金属和合金金属纳米颗粒，稀磁半导体和磁活性薄膜。这些材料具有作为新型磁活性胶体提取剂、体内成像剂、靶向磁性载体、磁性细胞分选器、传感器、高密度记录介质、基于自旋电子学的系统以及用于微机电和纳机电系统（MEMS/NEMS）的组件的应用。磁性测量系统提供的磁化测量能力和功能是真正独特的，将有助于加强波多黎各大学在纳米技术和材料科学与工程方面正在进行的和未来的研究工作。此外，在波多黎各没有类似的设备，这使得获得所要求的仪器成为推进大学研究目标的重要一步，也是对波多黎各研究基础设施的宝贵补充。 大学和几个少数民族服务机构之间通过纳米级的相互作用，结构和应用中心有很强的联系。

Through this grant, the University of Puerto Rico, Mayaguez will acquire a magnetic property measurement system that will support research and education efforts in nanotechnology and materials science and engineering. The system, based on a superconducting interference device, will allow accurate determination of direct current magnetic properties (including magnetic anisotropy) of magnetic powders and films, as well as bulk materials. The equipment will allow characterization of novel magnetically-active materials such as magnetic nanoparticle suspensions and powders, soft and hard ferrites, metal and alloyed metallic nanoparticles, diluted magnetic semiconductors, and magnetically-active thin films. These materials have applications as novel magnetically-active colloidal extractants, in-vivo imaging agents, targeted magnetic carriers, magnetic cell sorters, sensors, high-density recording media, spintronic based systems, and components for microelectromechanical and nanoelectromechanical systems (MEMS/NEMS). The magnetization measurement capabilities and functionalities afforded by the magnetic property measurement system are truly unique and will serve to enhance ongoing and future research efforts in nanotechnology and materials science and engineering at the University of Puerto Rico, Mayaguez. Furthermore, there are no similar devices available in Puerto Rico, making acquisition of the requested instrument a vital step in furthering the university's research goals, as well as a valuable addition to the Puerto Rico research infrastructure. There is a strong link between the university and several Minority Serving Institutions through the Nanoscale Interactions, Structures, and Applications Center.
