  • Patent number: 11917924
    Abstract: A multiplier device for binary magnetic applied fields uses Interlayer Exchange Coupling (IEC) structure where two layers of ferromagnetic material are separated from each other by non-magnetic layers of electrically conductive material of atomic thickness, sufficient to generate anti-magnetic response in a magnetized layer. A plurality of regions on a top surface are activated with a magnetic field in a first direction for a 1 value and in an opposite direction for a 0 value, the multiplication result presented as magnetic field direction on a plurality of output ferromagnetic regions.
    Type: Grant
    Filed: April 19, 2021
    Date of Patent: February 27, 2024

  • Patent number: 11641783
    Abstract: An adder device for binary magnetic applied fields uses Interlayer Exchange Coupling (IEC) structure where two layers of ferromagnetic material are separated from each other by non-magnetic layers of electrically conductive material of atomic thickness, sufficient to generate anti-magnetic response in a magnetized layer. A set of regions are positioned on a top layer above a continuous bottom layer, and the regions excited with magnetization for A and not A, B and not B, and C and not C to form a sum and an inverse carry output magnetization.

  • Patent number: 11355517
    Abstract: An AND or OR logic device has multiple layers of ferromagnetic material separated from each other by non-magnetic layers of electrically conductive material of atomic thickness, sufficient to generate anti-magnetic response in a magnetized layer. The anti-magnetic response in a layer below a layer magnetized with a polarity is summed in a region which is coupled to an output, the output generating at least one of a AND or OR logic function on applied input magnetization.
