    Abstract: The present invention is notably directed to a spin-orbit coupled device. This device comprises a confinement part. It further includes a circuitry, having an input device, energizable to inject spin-polarizations to charge carriers in an input region of the confinement part. The circuitry further comprises an output device, usable to detect spin- polarizations of charge carriers in an output region of the confinement part. The confinement part may be is configured to subject charge carriers drifting therein to a non¬ linear spin-orbit interaction, which causes to rotate a spin polarization of the drifting charge carriers by an angle that depends non-linearly on momenta of such charge carriers. The circuitry may be configured to allow momenta of charge carriers drifting in the confinement part to be varied, while injecting spin-polarizations in the input region. Varying momenta allows spin-polarizations of drifting charge carriers to be rotated, owing to said non-linear spin-orbit interaction.

    Abstract: A one-transistor (1T), one-selector (1S), one magnetic tunnel junction (1MTJ), spin torque transfer (STT), spin Hall effect (SHE), magnetic random access memory (MRAM) may be configured to provide separate write current and read current paths. In such a configuration, the write current may pass through a SHE electrode disposed proximate the MTJ device. The direction of write current flow through the SHE electrode determines spin polarization of the write current, the magnetic field orientation of a free magnetic layer in the MTJ device, and consequently the resistance of the MTJ device. The write current can be at a level sufficient to cause the reliable storage of binary information in the MTJ device. The read current, at a lower level than the write current, passes through the MTJ.

    Abstract: Aspects described herein are related to spintronic logic gates employing a Giant Spin Hall Effect (GSHE) magnetic tunnel junction (MTJ) element(s) for performing logical operations. In one aspect, a spintronic logic gate is disclosed that includes a charge current generation circuit and a GSHE MTJ element. The charge current generation circuit is configured to generate a charge current representing an input bit set. The input bit set may include one or more input bit states for a logical operation. The GSHE MTJ element is configured to set a logical output bit state for the logical operation, and has a threshold current level. The GSHE MTJ element is configured to generate a GSHE spin current in response to the charge current and perform the logical operation on the input bit set by setting the logical output bit state based on whether the GSHE spin current exceeds the threshold current level.
