Spin Pumping and Inverse Spin Hall Voltages from Dynamical Antiferromagnets

Abstract

Dynamical antiferromagnets pump spins efficiently into adjacent conductors as ferromagnets. The high antiferromagnetic resonance frequencies represent a challenge for experimental detection, but magnetic fields can reduce these resonance frequencies. We compute the inverse spin Hall voltages resulting from dynamical spin excitations as a function of a magnetic field along the easy axis and the polarization of the driving AC magnetic field perpendicular to the easy axis. We consider the insulating antiferromagnets MnF${}_2$, FeF${}_2$, and NiO. Near the spin-flop transition, there is a significant enhancement of the DC spin pumping and inverse spin Hall voltage for the uniaxial antiferromagnets MnF${}_2$ and FeF${}_2$. In the biaxial NiO, the voltages are much weaker, and there is no spin-flop enhancement of the DC component.
