Spatiotemporal Imaging of Magnetization Dynamics at the Nanoscale

Abstract

In this AFOSR project, we develop time-resolved magneto-thermal microscopy and apply it to materials and devices relevant to emerging magnetic memory and logic technologies. This technique is a spatiotemporal probe with sub 100 ps temporal resolution and high sensitivity to magnetic orientation. Because it uses heat rather than light as excitation source, it not limited by optical diffraction, and can obtain spatial resolution below 100 nm using a scanning probe without sacrificing temporal resolution.
