摘要

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 μm diamond we demonstrate the magnetic field sensitivity of around 18 nT/Hz^1/2.
