Abstract
A cryogenic magnetic device includes a free layer having a free magnetisation and a magnetic anisotropy favouring the orientation of the free magnetisation according to a first orientation or a second orientation, the magnetic anisotropy being defined by an energy barrier separating the first orientation and the second orientation, the amplitude of the energy barrier being less than 6300 k, the free layer having a Gilbert damping factor comprised between 0.02 and 0.4; a tunnel barrier extending in contact with the free layer; and a system configured to apply a voltage pulse through the tunnel barrier so as to reduce the amplitude of the energy barrier and switch the free magnetisation.
