Abstract

The sensitivity σ of an optically pumped quantum magnetometer is measured directly by comparing the output frequencies of 85Rb and 87Rb magnetometers integrated in a single two-isotope cell. The result σ87=59.6±6 fT Hz−1/2 agrees well with the value σ light87 =53.7±2 fT Hz−1/2 obtained indirectly by measuring 87 the ratio of the resonance steepness to the shot noise of light.
