Abstract:
© 2018 IEEE. We present a scaled device based on magnetic domain wall (DW) transport for logic applications. The device consists of multiple magnetic tunnel junctions (MTJs) connected by the same magnetic free layer (FL). Magnetic domain walls are injected by spin-transfer torque (STT) at the input MTJs and are sensed by tunneling magnetoresistance (TMR) at the output MTJ after propagation through the FL. Logic functions can be built by merging several domain walls. By enabling real-time detection of long range DW transport, we demonstrate a spintronic component which can be used for either Boolean or non-Boolean logic.
