During my Fulbright fellowship at TU Eindhoven in the Netherlands, I worked on developing an apertureless Scanning Near-field Magneto-Optic Microscope (apertureless SNMOM) with pico-second temporal and sub-wavelength spatial resolution. This device would aid in understanding the spin dynamics in small domains of ferromagnetic ultra-thin films. Our aperturless SNMOM achieves high spatial resolution by local light scattering from a nanometer-sized tip. It will measure the local magnetic field from the Faraday-rotation of polarized light passing through the sample.
