NOFCO - NOvel Features of Complex Oxides

About the project

Complex oxides exhibit a wide range of properties that give rise to a number of applications within future energy and IC technologies. The scientific program of this project addresses structure-property relations of Ruddlesden Popper type oxides, and with focus on three challenging themes that represent novel directions:

- Tuning of electronic and structural properties as basis for novel phenomena in Ln4Ni3O8 and Ln1+xSr3-xFe3O8 (Ln = rare earth element) based materials

- Water absorption in oxygen defect complex oxides; understanding mechanisms as basis for new compounds with tunable chemistry

- Epitaxial thin films of RP3 oxides - exploring anisotropic properties

It is emphasized that synthesis, characterization, advanced diffraction experiments and computational modeling will be closely interwoven in these efforts. This is firmly believed to enhance the scientific output of the project, both with respect to quality and quantitative wise. The project will involve significant national (IFE) and international collaboration (France, UK, India). In particular the collaboration with IFE at Kjeller will contribute to increased use of neutron scattering techniques in Norway, being of relevance in a long term perspective towards ESS.


Primary objectives

The overall aim of the project is to develop a solid understanding of crystal structure - electronic property relations in complex oxides through integrated activities between theory and experiments.

Secondary objectives

  • Derive new Ruddlesden-Popper type oxides with interesting electronic properties
  • Strengthen synthetic methodologies for preparation of novel RPs with strict control on oxygen vacancy ordering, cation substitution and ordering, water intercalation
  • Combine a variety of synthetic approaches, use SXRD/PND/TEM, EXAFS/XPS, TGA-DSC and theoretical modeling to help navigating experimental conditions into electronically interesting regions in relevant phase diagrams
  • Develop solid understanding of underlaying water intercalation mechanisms of RPs
  • Prepare for the first time, 1-2 RP thin films using ALD, and correlate 2D versus bulk electronic properties
  • Educate 1 PhD and train 1 PostDoc
  • Publish at least 10 publications in high impact journals


Financed through the FRINATEK program at the Norwegian Research Council
