"I began my research career when I was placed under Dr. Wei’s guidance through the University of Florida’s Student Science Training Program (SSTP). I continued researching in his laboratory when I came back to the UF. Ever since, I have wanted to conduct an independent project, present my research at national conferences, and publish my findings. Applying to the University Scholars Program allows me to fulfill all of these goals."

Research Description

Magneto-optical Properties of Anisotropic Magnetic-Plasmonic Heterostructures
In recent decades, the demand for faster information has encouraged photo-induced demagnetization has become a popular alternative to conventional magnetic reversal methods. To overcome practical limitations associated with lasers, researchers have incorporated noble metals such as gold (Au) with magnetic materials (Fe) to exploit their potentially synergistic magneto-optical (MO) properties. Noble metal nanoparticles exhibit localized surface plasmon resonance (LSPR), a resonant oscillation of the incident excitation and their conduction electrons, to create an enhanced electric field. Previous studies have mainly focused on the MO effects of the plasmonic shell on magnetic cores through Faraday rotation, which probes the degree of rotation of incident polarized light transmitted through a magnetic substance. However, Faraday rotation is an indirect measurement of the magnetic properties of nanoparticles. An experimental approach with the capability of probing the magnetic response while simultaneously exciting the plasmonic resonance of the noble metal will provide a better understanding of the MO effects. We plan to observe and understand how an anisotropic plasmonic shell’s LSPR directly affects the magnetic response of a magnetic-plasmonic heterostructures.
