| Summary: | The objective of this work is to develop a magnetic sensor, for space applications. Using magnetic field modulation with a MEMS resonator, it is possible to reduce the noise floor of a commercial Tunnelling Magnetic Resistor by two orders of magnitude, in the ultra-low frequency range. Low noise at this frequency range (below 10 nT/?Hz) is a strong requirement in planetary or space exploration missions like LISA (Laser Interferometer Space Antenna), where the observed gravitational waves will be in the 0.1 mHz to 0.1 Hz range. It will be shown that the noise spectral amplitude after demodulation is below 3 nT/?Hz in the whole frequency range, and therefore the objectives of the project are fulfilled successfully. |
