Quantum Dipolar Magnon Drag in Conducting Magnetic Bilayers
Abstract
We predict electrical drag between two electrically isolated metallic ferromagnets mediated by quantum dipolar magnon coupling. A charge current in one layer generates a nonequilibrium magnon current whose momentum is transferred across an insulating spacer through interlayer dipolar interactions. The resulting magnon current in the passive layer produces a measurable voltage through electron-magnon scattering. We show the combination of resonant quantum momentum transfer and magnetic tunability through the control of magnetization configurations distinguish quantum dipolar drag from conventional drag mechanism.
