An unconventional pathway to correlate the octahedral tilt coupling and spin-orbit reconstruction at oxide interfaces.

ABSTRACT: The direct experimental probing and detailed imaging of octahedral tilt, along with the control of magnetic ground state and spin-orbit occupancies in an artificially engineered heterointerface through the strain manipulation via interface engineering, is the long-standing challenging issue addressed here. We introduce an innovative methodology to measure the projected O-O-O angles (O-O-O_proj) between the neighboring in-plane BO₆ octahedra of perovskite oxide (ABO₃), demonstrating a precise quantification of strain-manipulated octahedral tilt in atomically engineered LaCoO₃ (LCO)/La_0.7Sr_0.3MnO₃ (LSMO) bilayer interfaces. The pronounced octahedral tilt on SrTiO₃ (STO) substrate (tensile strain) compared
