Abstract
A magnetic core for a magnetic field sensor is made from a material having a solid matrix in which are dispersed superparamagnetic particles, the solid matrix being chosen so as not to perturb the magnetic properties of the superparamagnetic particles, and so that the superparamagnetic particles represent a percentage P of the total volume of the core chosen to be greater than 2.5% or chosen in the span defined by the relation L 10%≦P≦L−1% where L corresponds to a threshold L beyond which the core loses the superparamagnetic properties. A magnetic field sensor that includes the magnetic core and an electronic circuit for measuring a magnetic field induced in the magnetic core.
