Spatiotemporal spin noise spectroscopy is combined with dynamic light scattering in order to reach spatial resolutions down $\ensuremath{\sim}\ensuremath{\lambda}/10$. Applied a system of localized electron spins, an insulating n-doped CdTe layer, this allows us reveal long jump distances $\ensuremath{\ell}\ensuremath{\sim}2.7\phantom{\rule{4.pt}{0ex}}\ensuremath{\mu}\mathrm{m}$. Spin spectra a...
