Abstract

We perform ultrafast Faraday holographic imaging to track the magnetization dynamics of perovskites in time and space. This interferometric imaging technique, based on off-axis holography, has the advantage of being shot-noise limited and allows us to get access to both amplitude and phase information of the measured signal. As a result, we can directly retrieve and disentangle the angular momentum and the spin components of the total magnetic moment inside the material. Here, we present our results on Methylammonium Lead Tribromide (MAPbBr3), a prototypical hybrid metal halide perovskite with captivating magnetic properties for future opto-spintronic applications.
