Abstract
Recent experimental advances now mean that it is possible to detect and probe single electronic spins with nanometre spatial resolution. This has implications for materials characterization at the single-atom level as well as for solid-state quantum computation. This paper focuses on the experimental issues regarding this technique, and on a simple model to explain the origin of the effect.
