TI  - Structural and magnetic properties of epitaxial iron oxide nanoislands on SrTiO3
M1  - FZJ-2023-01282

AB  - The chemical, electronic and magnetic properties of FexOy/oxide substrate heterostructures depend on substrate interactions and the flexible chemistry of the iron oxides, resulting in conductive or insulating, ferri- or antiferromagnetic phases. The reduced geometry of Fe3−δO4 nanoislands grown by reactive molecular beam epitaxy enables further tuning of electronic and magnetic properties for applications in catalysts and magnetoelectric devices [1]. We present the structural and magnetic characterisation of Fe3−δO4 nanoislands on (001) oriented SrTiO3 with mixed SrO/TiO2 and stepped TiO2 surface terminations by reflection high-energy electron diffraction (RHEED), grazing incidence small angle X-ray scattering (GISAXS) and SQUID magnetometry [2,3]. Our findings indicate the growth of crystalline, evenly shaped, ferrimagnetic islands. These results form the basis for further experiments probing the local electronic and magnetic structure of the nanoislands.[1] Y. Z. Chen et al., J. Appl. Phys. 103, 07D703 (2008), [2] G. E.
