The influence of a magnetic field on the capacitance of a glass-ceramic temperature sensor (Lake Shore CS-501GR) has been measured extensively at temperatures down to 0.09 K and magnetic fields up to 12 T. While the influence of a magnetic field is still negligible at 4 K, the sensor shows an increasing non-monotonic dependence on the magnetic field with falling temperature. The maximum relative change of capacitance with respect to the zero field value remains smaller than 5 · 10−4. However, with the given sensitivity of the sensor, this small magnetoeffect may not be ignored in the low temperature region.
