Alain Schuhl is a prominent inventor based in Clamart, France. He has made significant contributions to the field of magnetic field sensors, holding a total of 10 patents. His work has advanced the understanding and application of magneto-resistance in ferromagnetic materials.
Latest Patents
One of his latest patents is a magnetic field sensor that utilizes the magneto-resistance of ferromagnetic layers with parallel magnetic axes. This innovative magnetic detector comprises two thin-layer elements made of magnetic material, each possessing magnetic anisotropy in the plane. The design features two easy axes of magnetization, with a coercive field in one element differing from that of the other. The elongated shapes of these elements are mutually parallel and perpendicular to their easy magnetization direction in the absence of a magnetic field. This sensor is particularly useful for measuring magnetic fields.
Another notable patent is a magnetic field sensor and method for its fabrication. This sensor includes a layer of nonmagnetic insulator with ferromagnetic particles sandwiched between two ferromagnetic electrodes. The tunneling effect allows electrons to be transported between the electrodes and the ferromagnetic particles, with the tunneling resistance varying based on the orientation of the magnetization of the electrodes. This design enhances robustness and simplifies fabrication, addressing issues related to short-circuiting.
