Short summary
Fluxgate magnetometers are an important geophysical tool but are typically sensitive to changes in sensor temperature. We used a novel, low-cost calibration procedure to compare six matched sensors in which the material used as the mechanical support is varied and found that 30 % glass-filled PEEK engineering plastic is a good candidate for sensors. It is more economical, easier to machine, lighter, and more robust than historically used machinable ceramic.
