TLDR
It is demonstrated how interfacial interactions can induce a complex magnetic structure in a non-magnetic material and specifically show that exchange bias can unexpectedly emerge in heterostructures consisting of paramagnetic LaNiO3 (LNO) and ferromagnetic LaMnO 3 (LMO).Abstract:
Interfaces between insulating oxides have revealed exotic electronic and magnetic properties. It is now shown that a complex magnetic structure can emerge in an oxide superlattice, and that specific interfaces can unexpectedly exhibit exchange bias. The observations reveal the induction of antiferromagnetism in a material that is usually paramagnetic.read more

TL;DR: The quantum mechanical design and experimental realization of room-temperature polar metals in thin-film ANiO3 perovskite nickelates using a strategy based on atomic-scale control of inversion-preserving (centric) displacements is described and it is predicted that the geometric stabilization approach will provide novel avenues for realizing new multifunctional materials with unusual coexisting properties.

TL;DR: It is shown that distinct spectral signatures arise from a Ni 3d8 configuration along with holes in the oxygen 2p valence band, confirming suggestions that these materials do not obey a conventional positive charge-transfer picture, but instead exhibit a negative charge- transfer energy in line with recent models interpreting the metal–insulator transition in terms of bond disproportionation.
