Proposal Number: CTS-0102747Principal Investigator: S. MajetichInstitution: Carnegie Mellon U.Title: Coated Monodisperse Magnetic NanoparticlesABSTRACTThe proposed project is on fabrication of well-ordered coated monodispersed Fe nanoparticle arrays with enhanced magnetic and electronic coupling between particles. This will result in collective phenomena such as exchange ferromagnetism, insulator-to-metal transition, and extremely large magnetoresistance. The PI is focusing her effort in this project on preparation of ultrathin but impermeable coatings on Fe nanoparticles, precise control over interparticle spacing, nanoscale structure-property relationships and their correlation to larger length scales.

建议编号：CTS-0102747首席研究员：S.Majetich研究所：卡内基梅隆大学标题：包覆单分散磁性纳米粒子摘要拟议的项目是关于制备有序的包覆单分散铁纳米粒子阵列，粒子之间具有增强的磁耦合和电子耦合。这将导致集体现象，如交换铁磁性，绝缘体到金属的转变，以及极大的磁阻。PI在这个项目中的工作重点是在铁纳米颗粒上制备超薄但不透水的涂层，精确控制颗粒间距，纳米尺度的结构-性能关系，以及它们与较大长度尺度的关联。
