Abstract
Microfluxgate sensors are intended for the measurement of the very small variations of the earth magnetic field. Our sensors would present an output signal with a basic noise of about 1 nanotesla (nT)/√Hz, if an additional noise in the form of instabilities didn´t regularly occur, increasing the output noise by regular jumps of 100 nT in the output signal. Some solutions are presented here to reduce and finally to suppress this problematic noise.
