Abstract

Several types of fluxgate sensors were developed for measuring microvariations of the earth's magnetic field. Sensor cores were produced by etching, leading to better geometric homogeneity and long-term stability. This technology makes it possible to produce oval-shape sensors with both higher sensitivity and low noise.
