Abstract
A spintronic memory device having a spin momentum-locking (SML) channel, a nanomagnet structure (NMS) disposed on the SML, and a plurality of normal metal electrodes disposed on the SML. The magnetization orientation of the NMS is controlled by current injection into the SML through normal metal electrode. The magnetization orientation of the NMS is determined by measuring voltages across the NMS and the SML while flowing charge current through the SML via the normal metal electrodes.
