Spin-caloric resistance of Dirac plasma in a graphene Corbino device
arXiv:2404.03135 · doi:10.1103/PhysRevB.110.235303
Abstract
The thermal resistance of a spin-polarized hydrodynamic Dirac plasma in graphene is considered. A mechanism for the coupling of heat and spin flows is discussed, demonstrating that spin diffusion and spin thermocurrent modify viscous dissipation, leading to a significant enhancement of thermal resistance. Practical calculations are then presented for graphene devices in the Corbino geometry.
