  • Publication number: 20230145983
    Abstract: The disclosed technology relates to a magnetic domain wall-based memory device including a combination of at least one magnetic domain wall track and at least one spin orbit torque (SOT) track, which are arranged in a crossing architecture. The SOT track can include a first strip of a patterned SOT generating layer, wherein the first strip extends into a first direction and is configured to pass a first current along the first direction. The magnetic domain wall track can include a second strip of the patterned SOT generating layer and a first magnetic strip of a patterned magnetic free layer, wherein the second strip extends along a second direction and intersects with the first strip in a first crossing region. The first magnetic strip can be provided on the second strip including the first crossing region and can be configured to pass a second current along the second direction.

  • Patent number: 11599138
    Abstract: An arrangement for use in a matrix-vector-multiplier, comprising a stack of material layers arranged on a substrate, and a waveguide element formed in at least one material layer in the stack is disclosed. In one aspect, the arrangement further comprises a transducer arrangement which is coupled to the waveguide element. The transducer arrangement is configured to generate and detect spin wave(s) in the waveguide element, and wherein the waveguide element is configured to confine and to provide interference of the at spin wave(s) propagating therein. The arrangement further comprises a control mechanism comprising at least one control element coupled to the waveguide element, and a direct current electric source coupled to the at least one control element. The control mechanism, via the at least one control element, is configured to modify the phase velocity of the spin wave(s) propagating in the waveguide element.
