Description
The physical properties of an interface between two different materials are usually different from the bulk properties of both. Few experimental methods are capable of examining the local properties of such interfaces or near the surface as a function of depth on the nm scale. The low energy muons spin relaxation/rotation (LE-muSR) and beta-detected NMR techniques are perfectly suited for such studies. By implanting a highly spin polarized probes at a tunable energy, one can investigate the local magnetic properties in a depth resolved manner in thin films and hetero-structures. In this talk I will discuss some details of the techniques and present a few examples from applications in superconductivity, magnetism and dimensional effects at interfaces.
