Antiferromagnetic insulators can become active spintronics components by controlling and
detecting their dynamics via spin currents in adjacent metals. This cross talk occurs via spin
transfer and spin pumping, phenomena that have been predicted to be as strong in
antiferromagnets as in ferromagnets. Here, we demonstrate that a temperature gradient
drives a significant heat flow from magnons in antiferromagnetic insulators to electrons in
adjacent normal metals. The same coefficients as in the spin-transfer and spin-pumping …

Antiferromagnetic insulators can become active spintronics components by controlling and
detecting their dynamics via spin currents in adjacent metals. This cross-talk occurs via spin-
transfer and spin-pumping, phenomena that have been predicted to be as strong in
antiferromagnets as in ferromagnets. In a recent article, we demonstrate that a temperature
gradient drives a significant heat flow from magnons in antiferromagnetic insulators to
electrons in adjacent normal metals. The same coefficients as in the spin-transfer and spin …
