  • Control device for reversing the direction of magnetisation without an external magnetic field
    Publication number: 20040196744
    Abstract: The disclosure relates to a device for controlling magnetization reversal in a controlled ferromagnetic system such as a magnetic memory element, without using an external magnetic field, wherein it comprises between two flat electrodes a magnetic control part comprising, starting from the first electrode, a first ferromagnetic layer, a non-magnetic layer, and a second ferromagnetic layer, and the second of said two flat electrodes, the thickness of said second ferromagnetic layer being less than that of said first layer, and the thickness of said second electrode being sufficiently small to enable magnetic coupling between said second ferromagnetic layer and the system controlled by the control device.
