Patent ID: 8587044

Claim:
A complementary logic device comprising: an insulating layer formed on a substrate; a source electrode formed of a ferromagnetic body on the insulating layer; a gate insulating film formed on the source electrode; a gate electrode which is formed of a ferromagnetic body on the gate insulating film and controls a magnetization direction of the source electrode; a channel layer which is formed on each of a first side surface and a second side surface of the source electrode and transmits spin-polarized electrons from the source electrode; a first drain electrode formed of a ferromagnetic body on the first side surface of the source electrode with the channel layer interposed therebetween; and a second drain electrode formed of a ferromagnetic body on the second side surface of the source electrode with the channel layer interposed therebetween, wherein a magnetization direction of the first drain electrode and a magnetization direction of the second drain electrode are antiparallel to each other.
