摘要： A spin transistor having wide ON/OFF operation margin and producing less noise is provided. The spin transistor includes a substrate having a channel, a source, a drain and a gate formed on the substrate. The source and the drain are formed to have magnetization directions perpendicular to the length direction of the channel. The ON/OFF operations of the spin transistor can be controlled by generating a spin-orbit coupling induced magnetic field to have a direction parallel or anti-parallel to the magnetization directions of the source and the drain.

摘要： A magnetic memory device includes a substrate for reading and a magnetic memory cell. The substrate has a channel layer. The magnetic memory cell is formed on the substrate and has a magnetized magnetic material that transfers spin data to electrons passing the channel layer. Data stored in the magnetic memory cell are read by a voltage across both side ends of the channel layer that is generated when the electrons passing the channel layer deviate in the widthwise direction of the channel layer by a spin Hall effect.
