Spin orbit coupled 3d–5d quantum oxide heterostructures

The controlled synthesis of quantum oxide heterostructures provides tremendous opportunities in producing materials with remarkable physical properties and functionalities. We have successfully synthesized superlattices and heterostructures composed of 3d and 5d transition metal oxides (TMOs). These material systems are an ideal test bed to take advantage of the strong correlation in 3d TMOs and the spin orbit coupling in heavy-element 5d TMOs. To manipulate the Dzyaloshinskii-Moriya interaction in 3d-5d heterostructures, we engineered the interfaces between 3d and 5d TMOs, in such way to break the inversion symmetry. We will present our observations on exotic quantum phenomena, including charge transfer induced interfacial magnetism and topologically non-trivial spin textures, that are not present in the constituent materials.
