Magnetic-free nonreciprocal optical devices have attracted great attention in recent years. Here, we investigated the magnetic-free polarization rotation of light an atom vapor cell. Two mechanisms nonreciprocity been realized ensembles hot atoms, including electromagnetically induced transparency and optically-induced magnetization. For a linearly polarized input probe light, angle up to 86.4° has with external control pump laser powers 10 mW is mainly attributed magnetization effect. Our demonstration offers new approach realize devices, which can be applied solid-state may useful photonic integrated circuits.
