Title:
SPIN ACCUMULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/225160
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of providing a spin accumulation device for which the accumulation characteristics and supply characteristics of spin electrons are excellent, and which can operate at room temperature. [Solution] A spin accumulation device 1 is characterized by including: a substrate 2; a superlattice layer 4 which is disposed on the substrate and in which alternatingly and repeatedly layered are a topological insulation layer 4a having topological insulation properties, and an electrical insulation layer 4b having electrical insulation properties; and a magnetic electrode 5 which is disposed on the superlattice layer 4 and which has a linear section 5a that bridges points on the outer edge 2 of the surface of the superlattice layer 4.
