| 摘要 |
A device comprising: an assembly consisting of two, respectively upper and lower thin layers each forming a ferromagnetic element and separated by a thin layer forming a non magnetic element, said assembly being made up so that the layers forming the ferromagnetic elements are magnetically coupled through the layer forming a non magnetic element; an electrode, a layer forming a ferroelectric element in which the polarization may be oriented in several directions by applying an electric voltage through said layer, said layer forming a ferroelectric element being positioned between the layer forming a lower ferromagnetic element and the electrode; said device being configured so as to allow control of the magnetic configuration of the layers forming ferromagnetic elements by the direction of the polarization in the layer forming a ferroelectric element. |
