      abstract     = {Ruderman-Kittel-Kasuya-Yosida interaction(1-3) is an
                      indirect magnetic coupling between localized spins in a
                      non-magnetic host mediated by conduction electrons. In
                      diluted systems it is often the dominating magnetic
                      interaction and has played a key part in the development of
                      giant magnetoresistance devices(4,5), drives ferromagnetism
                      in heavy rare-earth elements(6) aswell as in diluted
                      magnetic semiconductors(7) and gives rise to complex
                      magnetic phases such as spin glasses(8). For bulk systems,
                      an isotropic and continuous model of Ruderman-Kittel-Kasuya
                      Yosida interaction is often sufficient. However, it can be
                      misleading in magnetic nanostructures consisting of separate
                      magnetic atoms adsorbed on the surface of a non-magnetic
                      material. Here, an atomically precise map of the magnetic
                      coupling between individual adatoms in pairs is measured and
                      directly compared with first-principles calculations,
                      proving that Ruderman Kittel-Kasuya-Yosida interaction is
                      strongly directional. By investigating adatomtriplets of
                      different shapes we demonstrate that the map can serve to
                      tailor the magnetism of larger nanostructures.},
