For years, the nitrogen-vacancy (NV) center in diamond has been in the spotlight for studies of electron spin oupling. Also the coupling to other nearby color centers in diamond was studied recently. We will explore single atom control techniques for sensing external spins and imaging them using scanning probe microscopy. External magnetic fields cause a frequency shift of the electron spin resonance of our NV-center, which is detectable by Optically Detected Magnetic Resonance (ODMR). One single NV-center located in a diamond tip is the main part of the future Atomic-Force- and Magnetic-Resonance-Microscope (AFM/MRM). Due to the possibility of single-spin detection with NV-centers under ambient conditions, this combination of AFM and MRM is planned to work even at room temperature but also at low temperature (4K). We will be able to locate single spins on the nanoscale.
