This circuit () includes: an intermediate layer (), made from a conductive material and configured according to a pattern; a first electrode and a plurality of electrodes, which includes at least second and third electrodes (), each electrode including: A polarizer, made from a ferromagnetic material, placed at a particular point of the pattern of the intermediate layer, and having a magnetization; A superconducting layer, made of a superconducting material, arranged on the polarizer; and a control means () able to modify the magnetization of the polarizer of the second electrode; another control means () able to modify the magnetization of the polarizer of the third electrode; bias terminals for applying a bias signal; and, terminals for measuring an output signal, a level of the output signal being correlated with a mutual orientation of the first, second and third magnetizations.

Logic circuit based on spin valves of the spin-polarized supercurrent type and circuit integrating such logic gates

An electrically adjustable memory effect resistor comprises a stack comprising a superconductive material extending along an axis, a ferroelectric material and a conductive third material. The adjustable resistor comprises a means for controlling electrical voltage allowing an electric field to be generated between the superconductive material and the conductive material allowing the polarization direction of the ferroelectric second material to be modified. The adjustable resistor furthermore comprises an electrically insulating material placed between the ferroelectric material and the conductive material, the thickness of the insulating material varying in a direction parallel to the axis&#x2014;so as to cause a variation in the electric field applied between the first layer and the third layer.
