Abstract
Antiferromagnetic (AFM) oscillators are of interest because of their potential to operate at THz frequencies, and thus to fill the ``terahertz gap''. Previous studies on AFM oscillators have focused on using the spin Hall effect to generate spin current, but other mechanisms exist. Here the authors investigate using spin current with an arbitrary polarization direction that is not simply due to the spin Hall effect. Their results will be useful for application of such oscillators, and more broadly for understanding AFM spin dynamics.
