Abstract
A logic device includes: a substrate having a channel layer; two input terminal patterns of ferromagnetic material formed on the substrate and spaced apart from each other along a longitudinal direction of the channel layer so as to serve as the input terminals of a logic gate; and an output terminal pattern of ferromagnetic material formed on the substrate and disposed between the two input terminal patterns to serve as an output terminal of the logic gate. The output terminal pattern reads an output voltage by using spin accumulation and diffusion of electron spins which are injected into the channel layer from the input terminal patterns.
