A next-generation room-temperature AFM setup with optical access for NV-magnetometry — •Dominik Schmid-Lorch, Tobias Staudacher, Friedemann Reinhard, and Jörg Wrachtrup — 3. Physikalisches Institut und Forschungszentrum SCoPE, Universität Stuttgart, Germany

The nitrogen-vacancy (NV) color center in diamond can be used as a magnetic field sensor with sub-nanometer special resolution. This is due to the fact that its spin sublevels are sensitive to magnetic fields and that they can be monitored using optically detected magnetic resonance (ODMR). Using this center as a scanning probe in an AFM [1] the sensing and imaging of single spins under ambient conditions might be feasible.

We present a novel integrated design for such a scanning probe diamond nano-magnetometer as well as our planed experiments, such as single spin MRI and single molecule SNOM.
