Abstract: We create a working model of a magnetometer of a new type that is based on using cross-relaxation resonances in ensembles of NV-centers in diamond. This type of magnetometer does not require microwave radiation. For a sensor made out of a 300 micron diamond we demonstrate the magnetic field sensitivity of around 18 nT/Hz$^{1/2}$.
Keywords: cross-relaxation, NV-center, quantum magnetometer.
