Isolated magnetic atoms doped into a semiconductor represent an interesting system for spintronics applications and a possible means of constructing quantum bits. So far, however, it has not been possible to study the correlation between the local atomic structure and the dopant's magnetic properties. Here, sensitive scanning probe techniques have been developed that allow the spin excitations of individual magnetic dopants within a two-dimensional semiconductor system to be measured.
