Abstract

(LaNiO₃)_n/(LaMnO₃)₂ superlattices were grown using ozone-assisted molecular beam epitaxy, where LaNiO₃ is a paramagnetic metal and LaMnO₃ is an antiferromagnetic insulator. The superlattices exhibit excellent crystallinity and interfacial roughness of less than one unit cell. X-ray spectroscopy and dichroism measurements indicate that electrons are transferred from the LaMnO₃ to the LaNiO₃, inducing magnetism in LaNiO ₃. Magnetotransport measurements reveal a transition from metallic to insulating behavior as the LaNiO₃ layer thickness is reduced from five to two unit cells and suggest an inhomogeneous magnetic structure within LaNiO₃.
