This work determines the drag current of two metallic layers separated by a ferromagnetic insulator layer by using the semiclassical Boltzmann approach with proper boundary conditions of electrons and magnons at the metal-FI interface.Abstract:
In a semiconductor heterostructure, the Coulomb interaction is responsible for the electric current drag between two 2D electron gases across an electron impenetrable insulator. For two metallic layers separated by a ferromagnetic insulator (FI) layer, the electric current drag can be mediated by a nonequilibrium magnon current of the FI. We determine the drag current by using the semiclassical Boltzmann approach with proper boundary conditions of electrons and magnons at the metal-FI interface.read more

Long-distance transport of magnon spin information in a magnetic insulator at room temperature
TL;DR: In this paper, the authors studied the diffusion and relaxation of spin in a magnetic insulator, where the large bandgap prohibits the motion of electrons, but spin can still be transported through the diffusion of non-equilibrium magnons, the quanta of spinwave excitations in magnetically ordered materials.

TL;DR: Tunable spin transport over long distances is demonstrated through the antiferromagnetic insulator haematite, paving the way to electrically tunable, ultrafast, low-power, antiferromeagnetic-insulator-based spin-logic devices6,13 that operate without magnetic fields at room temperature.
