Abstract Complex oxides show extreme sensitivity to structural distortions and defects, the intricate balance of competing interactions which emerge at atomically defined interfaces may give rise unexpected physics. In non-magnetic complex oxides, one most intriguing properties is emergence magnetism sensitive chemical defects. Particularly, it unclear defects are responsible for emergent magnetic interfaces. Here, we direct clear experimental evidence, supported by theoretical explanation,...

Abstract The metallic interface between two oxide insulators, such as LaAlO 3 /SrTiO (LAO/STO), provides new opportunities for electronics and spintronics. However, due to the presence of multiple orbital populations, tailoring interfacial properties ground state metal‐insulator transitions remains challenging.

Magnetic proximity-induced magnetism in paramagnetic LaNiO3 (LNO) has spurred intensive investigations the past decade. However, no consensus been reached so far regarding magnetic order LNO layers relevant heterostructures. This paper reports a layered ferromagnetic structure for (111)-oriented LNO/LaMnO3 (LMO) superlattices. It is found that each period of superlattice consisted an insulating LNO-interfacial phase (five unit cells thickness, ∼1.1 nm), metallic LNO-inner phase, poorly...
