We demonstrate that it is possible to resolve magnetic properties of small clusters buried up to 1.5 nm deep beneath a metallic surface. The possibility of deducing magnetic properties of buried nanostructures by studying polarization maps of the surface is discussed. Moreover, we show that there is a way to determine the coupling of buried structures to each other by studying the polarization of electrons in vacuum space above the system.
