Claim:
1. An integrated magnetometer comprising a plurality of multilayer magnetoresistive sensors (R 1 , R 2 , R 3 , R 4 ) deposited on a top surface of a substantially planar substrate ( 2 ), wherein: said top surface of the substrate presents at least one cavity or projection (P, CP) having a plurality of inclined faces; at least four of said multilayer magnetoresistive sensors are deposited on four of said inclined faces of the at least one cavity or projection, said magnetoresistive sensors presenting four different orientations opposite in pairs, each sensor being sensitive to an external magnetic field component that is parallel to the face on which it is deposited; said or each cavity or projection presents the shape of a pyramid or a truncated pyramid, having a base which is square or rectangular; and the sensitivity axes (A
