AbstractUsing spin-assisted ab initio random structure searches, we explore an exhaustive quantum phase diagram of archetypal interfaced Mott insulators, i.e. lanthanum-iron and lanthanum-titanium oxides. In particular, we report that the charge transfer induced by the interfacial electronic reconstruction stabilises a high-spin ferrous Fe2+ state. We provide a pathway to control the strength of correlation in this electronic state by tuning the epitaxial strain, yielding a manifold of quantum electronic phases, i.e. Mott-Hubbard, charge transfer and Slater insulating states. Furthermore, we report that the electronic correlations are closely related to the structural oxygen octahedral rotations, whose control is able to stabilise the low-spin state of Fe2+ at low pressure previously observed only under the extreme high pressure conditions in the Earth’s lower mantle. Thus, we provide avenues for magnetic switching via THz radiations which have crucial implications for next generation of spintronics technologies.

Based on the example of the p-type LaAlO3/SrTiO3 interface, we discuss charge-transfer phenomena that tailor the ionic conductivity along oxide heterointerfaces, by providing a confined space-charge layer as channel for oxygen ion conduction.

We have impregnated chromium(iii) onto a particulate niobium oxide to make bulk oxide–oxide interfaces, identifying by a combination of XPS and diffuse reflectance the energy of the metal-to-metal charge transfer transition that is responsible for the visible light photocatalytic decomposition of methyl orange.
