Magnons in antiferromagnets hold potential for chirality-based spintronics, but a practical platform remains absent. Here, the authors demonstrate possible magnon chirality switching, reading and modulation in an artificial ferrimagnet Py/Gd/Py/Gd/Py/Pt multilayer, manifesting the chirality as an independent degree of freedom.
