Physical Review A—Atomic, Molecular, and Optical Physics, 2013•APSWe demonstrate detection of a weak alternate-current magnetic field by application of the
spin-echo technique to F= 2 Bose-Einstein condensates. A magnetic field sensitivity of 12
pT/Hz is attained for an atom number of 5× 10 3 at a spatial resolution of 100 μ m 2. Our
observations indicate magnetic field fluctuations synchronous with the power supply line
frequency. We show that this noise is greatly suppressed by application of a reverse phase
magnetic field. Our technique is useful in order to create a stable magnetic field …

We demonstrate detection of a weak alternate-current magnetic field by application of the spin-echo technique to Bose-Einstein condensates. A magnetic field sensitivity of 12 pT is attained for an atom number of at a spatial resolution of 100 m. Our observations indicate magnetic field fluctuations synchronous with the power supply line frequency. We show that this noise is greatly suppressed by application of a reverse phase magnetic field. Our technique is useful in order to create a stable magnetic field environment, which is an important requirement for atomic experiments which require a weak bias magnetic field.
