a Creating emergent phases by an artificial assembly of two intrinsic functional phase I and II in oxide superlattices illustrated with simultaneous manipulation of spin (M), polar (P), even effective electric (E) or magnetic fields (H). b High angle annular dark-field (HAADF)-scanning transmission electron microscopy (STEM) images taken along the STO [010] zone axis at room temperature. c, d Atomically resolved HAADF and integrated differential phase contrast (iDPC) images, where the non-equivalent interfaces were constructed in the (Sr2IrO4)3/(SrTiO3)6 (I3/T6) superlattice, antiferromagnetic Sr2IrO4 (SIO) and dielectric SrTiO3 (STO) have been selected as functional Phase I and II.
