Temperature gradient —drives→ Spin Seebeck effect

Conditions

• 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
