Abstract
A fluxgate micro-magnetometer with perpendicular detection and a process of realization thereof. A ferromagnetic core is perpendicular to a substrate. The axes of excitation coils and pick-up coils are also perpendicular to the substrate. A magnetic field component which is perpendicular to the substrate is thus measured. The two other components can be measured by magnetometers of classical type whose core is parallel to the substrate. Such a device may find application in the domain of magnetic measurement, as an example.
