Core-Shell Magnetic Nanoparticles for Next Generation Optics and Communications

Professor: Amal El-Ghazaly

Project Description: Magnetic nanoparticles have shown great potential for a wide range of applications from data storage to medical imaging and even optics and millimeter wave communications. The interaction of electromagnetic waves and light with magnetic materials is highly dependent on the magnetic properties. Therefore, magnetic materials have the potential to dramatically manipulate the speed, direction, and even whether or not light can flow through the material. In this project the student will investigate the structure-property relationship of magnetic core-shell nanoparticles and develop a new magneto-optic material. More specifically, by systematically adjusting the synthesis parameters, we will be able to control the size of the core and the shell thickness. The structural and magnetic properties will be characterized by Scanning Electron Microscope, Transmission Electron Microscope, and Vibrating Sample Magnetometer. Micromagnetic simulation will be performed to further confirm the experimental results. The magneto-optical properties (magnetic field-controlled transmission of light) through the magnetic particles and monolayers of them will be evaluated towards the end of the project using a Faraday Microscope. During this project the student will learn about the colloidal chemistry, the structural and magnetic characterization techniques, micromagnetic simulation and the possible applications of magnetic nanoparticles.
