Coated Monodisperse Magnetic Nanoparticles

提案编号：CTS-0102747 首席研究员：S. Majetich 机构：卡内基梅隆大学 标题：涂层单分散磁性纳米颗粒 摘要 该项目旨在制造有序的涂层单分散铁纳米颗粒阵列，并增强颗粒之间的磁性和电子耦合。 这将导致诸如交换铁磁性、绝缘体到金属转变和极大磁阻等集体现象。 该项目负责人的重点是在铁纳米颗粒上制备超薄但不渗透的涂层、精确控制颗粒间距、纳米级结构-性能关系及其与更大长度尺度的相关性。

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.
