  • Integrated magnetometer and its manufacturing process
    Patent number: 9557392
    Abstract: Integrated magnetometer comprising a plurality of multilayer magnetoresistive sensors deposited on a surface, called the top surface, of a substantially planar substrate, characterized in that said top surface of the substrate has at least one cavity or protuberance provided with a plurality of inclined faces, and in that at least four said magnetoresistive sensors are placed on four said magnetoresistive sensors are placed on four said inclined faces, having different orientations and opposite one another in pairs, each sensor being sensitive to one component of an external magnetic field parallel to that face on which it is placed. Process for manufacturing such a magnetometer.
    Type: Grant
    Filed: January 28, 2011
    Date of Patent: January 31, 2017

  • Magnetic recording device, especially for a hard disk and its manufacturing process
    Patent number: 8036070
    Abstract: A magnetic recording device comprising at least one unstructured recording support exhibiting at least one elementary magnetic layer, the recording support having a magnetization perpendicular to the plane of the support characterized in that it comprises magnetic elements having a magnetization perpendicular to the plane of the support and a greater inversion field than the inversion field of the recording support, and which are separated from the recording support by a decoupling layer made of a nonmagnetic material so that the magnetic elements produce a dipolar field in the recording support. The magnetic elements are spaced apart from one another by nonmagnetic regions, each magnetic element defining during a write operation a memory point in the recording support.
