Abstract
A thermoelectric conversion device includes: a substrate; two magnetic layers having a fixed magnetization direction with respect to the substrate; and at least one electrode including a material having a spin orbit interaction, wherein a gap (or dielectric layer of low thermal conductivity) is provided between the magnetic layers. A thickness of the gap (or dielectric layer) is of a distance within the range at that a magnetic dipole interaction is exerted, and a film thickness of the magnetic layers is of about a characteristic length determined by diffusion or the like of a magnetic excitation.
