Abstract:
1. A spin MOS field-effect transistor comprising, in at least one of a source and a drain, a structure including: an MgO layer formed on a semiconductor substrate; a first ferromagnetic layer formed on the MgO layer and having a body-centered cubic lattice structure; a Cr layer formed on the first ferromagnetic layer and having the body-centered cubic lattice structure, the Cr layer having a film thickness of 3 nm or less; a Heusler alloy layer formed on the Cr layer and having one of a B2 structure and an L2 a barrier layer formed on the Heusler alloy layer; and a second ferromagnetic layer formed on the barrier layer.
