AB  - Research and Teaching Oxide MBE System at JCNS-2 Forschungszentrum JülichThe Jülich Centre for Neutron Science develops and uses scattering methods for research into structural andmagnetic order of functional materials. The Oxide Molecular Beam Epitaxy (OMBE) laboratory at JCNS-2provides students and JCNS scientists with a powerful platform to study and realize the growth of thin filmmagnetic materials. Thin films grown in this system can then be analyzed using the scattering tools availableat our institute or further afield at large scale neutron and x-ray synchrotron facilities. Our OMBE has 6effusion cells and 2 electron guns with 4 sources each for electron beam evaporation, as well as a plasmasource for oxide growth. In-situ Reflection High Energy Electron Diffraction (RHEED) is available for surfacestructure and growth mode analysis. On a vacuum buffer line attached to the main chamber, we also areable to provide Low Energy Electron Diffraction (LEED) surface structure analysis of vacuum annealedsubstrates and as-grown films, as well as Auger Electron Spectroscopy (AES) for sample chemical analysis.For introduction to thin film growth methods, the OMBE is also used as a teaching tool for the RWTH Aachenas part of the JARA-FIT laboratory course. Students in 2020 had their first encounter with a complex oxidesystem through a virtual lab course. Doctoral students use the system to grow their own thin films for lateranalysis with x-ray and neutron facilities and to fundamentally understand the materials growth process.Students at the Forschungszentrum Jülich who use the neutron facilities at MLZ in Garching have theadvantage that a sister MBE system is available there for on-site film growth with a vacuum transfer systemto a neutron reflectometer (MARIA). Highlights in this poster will include recent projects such as;73 stoichiometric tuning of strontium cobaltite and a reproducibility study between the two sister MBE’s, domainpattern control of iron palladium thin films, and strain and interfaces in lanthanum strontium manganitepiezoelectric heterostructures (LSMO/PMN-PT).
