Interface engineering in transition metal oxide heterostructures not only gives rise to exotic physical phenomena, but also has potential applications in spintronics. In this study, we demonstrate the appearance of strong interfacial coupling in 5dparamagnetic SrIrO3and 3dferromagnetic La0.67Sr0.33MnO3bilayers, which manifests itself in the dramatic enhancement of coercivity by about 70 times larger than that of the single La0.67Sr0.33MnO3layer and the observation of an unexpected exchange bias effect up to 40 K. Systematic magnetic analysis further reveals the emergence of an interfacial spin glass state in this 5d-3doxide bilayer. This interfacial-coupling-induced spin glass state is the underlying origin of the unconventional exchange bias effect rarely observed in paramagnetic/ferromagnetic heterostructures.
