In recent years the nitrogen-vacancy (NV) center in diamond has emerged as a versatile sensor for magnetic fields, temperature, pressure or electric fields.
As a large quantity of them can be contained in a single diamond, NV centers are especially suitable for performing high precision measurements in very confined spaces. Such highly sensitive local probes would allow for interesting applications in ultracold quantum gas experiments when placed in immediate vicinity to the atoms.
In this poster we present our first steps towards this, using Nitrogen-Vacancy centers to stabilize and control the magnetic fields in our experiment up to 500 G.
