Thermal magnon transport in FM/AFM bilayers
The study investigates how thermal gradients drive spin currents between a ferromagnetic (FM) and antiferromagnetic (AFM) bilayer. It found that a thermally triggered spin current appears in the AFM, which is unusual for bulk materials. This transport is chirality-selective, meaning only specific magnon modes flow unidirectionally from the FM to the AFM, acting like a spinwave filter.
