Patent ID: 7969762

Claim:
A spintronic device, comprising: a first ferromagnetic structure including a first magnetic switching zone, said first ferromagnetic structure comprising at least one first magnetic domain in which the magnetic moments M are all aligned in a first direction and a second magnetic domain in which the magnetic moments are all aligned in a second direction different than the first direction, the first magnetic domain being separated from the second magnetic domain by a first magnetic domain wall, said first ferromagnetic structure including means for stabilizing said first magnetic domain wall in two stable positions, the first magnetic switching zone being located between these two stable positions, said first magnetic domain wall being able to move from the first stable position to the second stable position by the combined effect of a first current of spin-polarized carriers passing through said first ferromagnetic structure and a magnetic field, the field lines of which pass through the first magnetic switching zone so as to be approximately parallel to the direction of the first current, at least the first current or the magnetic field being variable and said first magnetic switching zone thus belonging either to the first magnetic domain or to the second magnetic domain; and the spintronic device including a first magnetic element, the magnetic moments of said first magnetic element not being coupled with the magnetic moments of the first magnetic switching zone.
