This project aims to produce, model and probe Naturally Layered Perovskites, providing new efficient materials for sustainable energy conversion. It will explore the possibilities to adjust oxygen octahedra rotations to create acentricity in Ruddlesden-Popper and double perovskite oxides enabling room temperature magneto-electric coupling or negative thermal expansion. The project will focus in the incorporation of multiple cations into Ca3(Mn,Ti)2O7 and AA BMnO6. Using methods including non-equilibrium approaches such High-Pressure or Pulsed-Laser Deposition we will engineer crystallographic phases with adjusted lattice, electric and magnetic interactions. The overall study will comprehend the theoretical modeling of the systems, their characterization by conventional macroscopic techniques and by a combination of exquisite local probe ones. Significant impact on unveiling strategies for materials functionalization far beyond state-of-the-art is foreseen.
