Detection of a weak magnetic field with high spatial resolution is an important technique, which enables various applications in a wide range of fields, from fundamental physics to medical technology. We address the realization of this technique by using atomic gaseous Bose-Einstein condensates with internal spin degrees of freedom. Here, we describe the latest research developments in our group, especially for the detection of alternate-current magnetic fields using a spin-echo-based magnetometer.
