Abstract

We report strong coupling between magnons and cavity photons in a single-crystalline slab of α-Fe2O3 (hematite) with canted antiferromagnetic order at room temperature. The hybridized magnon polaritons propagate over many millimeters due to their high group velocities, as experimentally characterized using time-of-flight spectroscopy. The conventional dipolar and spin-orbit-interaction-induced chirality can explain an observed nonreciprocity. Our findings highlight the potential of antiferromagnetic magnon polaritons for on-chip spin-based information technologies.
