ABSTRACT:
A memory element, logic element or sensor element is provided, which element comprises a switchable first magnetic component exhibiting a ferromagnetic or ferrimagnetic behaviour and comprising at least two magnetic domains with different magnetization directions and a domain wall between the magnetic domains. The element has electrodes operable to induce an electric current which at least partially flows through the domain wall with a current density high enough to cause the domain wall to reversibly propagate within the magnetic component. The first magnetic component may belong to a layered system further including a second magnetic component with a fixed magnetization and a non-magnetic spacer layer arranged between the first and second magnetic component. In such a layered system, the electrical resistance may depend on the relative orientation of the magnetization directions of the first and second magnetic component, due to the GMR or TMR effect.
