| Abstract: | We present a portable four-channel atomic magnetometer array operating in the spin-exchange relaxation-free regime. The magnetometer array has several design features intended to maximize its suitability for biomagnetic measurement, specifically foetal magnetocardiography, such as a compact modular design and fibre-coupled lasers. The modular design allows the independent positioning and orientation of each magnetometer. Using this array in a magnetically shielded room, we acquire adult magnetocadiograms. Thesemeasurements were taken with a 6-11 fT Hz-1/2 single-channel baseline sensitivity that is consistent with the independently measured noise level of the magnetically shielded room.
