Atomic magnetometer (AM) operated in a spin-exchange relaxation-free (SERF) regime features superior sensitivity and non-cryogenic operation,and thus is competitive with the best superconducting quantum interference devices.Previously,SERF AM with fT/Hz1/2 level sensitivity commonly acted as a single-axis sensor.Here we demonstrate a dual-axis SERF AM capable of simultaneously and independently detecting x-and y-field components with a sensitivity of 20 fT/Hz1/2.As there is no necessity to worry about the cross-talk effects arising from field modulations,the dual-axis scheme proposed here is of particular interest to AM array and hence the biomagnetic applications.
