Abstract
A novel sensor design for a Hanle vector magnetometer is presented. Linearly and circularly polarized light beams are used in parallel to enable magnetic field measurements with an isotropic noise floor that is stable down to 10⁻¹ Hz. The level is three times lower compared to a state-of-the-art fluxgate magne-tometer at 1 Hz. The first functional test shows no intrinsic crosstalk between the sensor axes. With the possibility to add an absolute scalar measurement mode, this sensor has the potential to replace the combination of a fluxgate and absolute reference magnetometer on space missions.
