WRITABLE MAGNETIC ELEMENT

摘要

The invention relates to a writable magnetic element comprising a stack of layers presenting a write magnetic layer, wherein the stack has a central layer of at least one magnetic material presenting a direction of magnetization that is perpendicular to the plane of the central layer, said central layer being sandwiched between first and second outer layers of non-magnetic materials, the first outer layer comprising a first non-magnetic material and the second outer layer comprising a second non-magnetic material that is different from the first non-magnetic material, at least the second non-magnetic material being electrically conductive, and wherein it includes a device for causing current to flow through the second outer layer in a current flow direction parallel to the plane of the central layer, and a device for applying a magnetic field along a magnetic field direction that is perpendicular to the plane of the central layer.
