On-demand manipulation of these symmetries remains challenging. Here, we demonstrate a strategy to control the in-plane mirror symmetries of interfaces by engineering the crystallographic orientation of heterostructures. We design a workhorse system with a new orientation, i.e., the LaAlO3/SrTiO3 heterostructure with metallic interfaces in the (112)-plane. Such a high index orientation leads to the breaking of all the pristine mirror symmetries except the mirror plane perpendicular to the [1 -1 0] direction (M[1 -1 0]), resulting in the Cs point symmetry with a metallic conduction. Consequently, this interface exhibits a giant nonlinear Hall effect characterized by a large Berry curvature dipole, a circular photogalvanic effect, and current-induced out-of-plane magnetization, all functional at room temperature. The magnitude of the nonlinear Hall effect rivals theWeyl and Dirac systems. Our work establishes a new strategy in exploring emerging electronic properties with nontrivial quantum geometry by designing the interface symmetry. 2025-11-01T00:00:00Z Dataset Dataset 10.82444/warw.33907789.v1 https://figshare.com/articles/dataset/Data_for_Magnetization_generation_and_giant_nonlinear_transport_at_symmetry-engineered_interfaces/33907789 CC BY 4.0
