Coated Monodisperse Magnetic Nanoparticles

提案编号： CTS-0102747主要研究者：S. Majetich机构： 卡内基梅隆大学 包覆单分散磁性纳米粒子摘要本项目旨在制备有序的包覆单分散铁纳米粒子阵列，增强粒子间的磁性和电子耦合。 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在该项目中的工作重点是在Fe纳米颗粒上制备可渗透但不可渗透的涂层，精确控制颗粒间间距，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.
