Spin Seebeck effect
A temperature gradient in a magnet, including a magnetic insulator, drives a magnon current that pumps a spin current into an attached metal.

Relations
- a magnetised ferromagnet, metallic or insulating (YIG), under a temperature gradient
- an adjacent spin sink (heavy-metal layer) is needed for the usual electrical detection through inverse spin Hall conversion, not for the spin-Seebeck response itself
- magnon current pumps a spin current into the adjacent metal across the interface
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
