Abstract: Thin film heterostructures are essential in modern device development, offering a platform for manipulatinginterfacial effects. Molecular Beam Epitaxy (MBE) is an indispensable technique for the growth of high-quality epitaxial films, heterostructures, and nanostructures. It enables precise controlover the composition, thickness, and structure of materials and has led to the discovery of a widerange of complex interface behaviors; including two-dimensional electron gases (2DEGs), quantumconfinement, magnetism, superconductivity, and topological insulators. These interface effects resultin unique electronic, optical, and magnetic properties, making them of interest for both fundamentalresearch and technological applications.JCNS operates two MBE systems: An oxide MBE at JCNS-2 in Jülich, and an MBE at MLZ in Garching.Both systems are available to JCNS scientists, with the Garching instrument also available to abroader scientific community through a proposal system for thin film growth.Here we highlight ongoing projects using our MBE facilities: Variable (perpendicular magneticanisotropy) PMA in FePd, magnetite on Nb-doped strontium titanate, Co/Pd multilayers on silicananospheres, and multilayers of oxide and non-oxide ferromagnets and metals for skyrmion latticesand other magnetic textures.Additionally, x-ray and neutron scattering experiments on MBE-grown structures are powerful toolsfor investigating complex interfaces; enabling probing of structural, magnetic and electronic propertieswith high resolution. This can lead to new insights into the behavior of electrons, phonons,and spin waves in these systems, and help to elucidate the underlying physical mechanisms. Theunique positioning of our MBE instruments provides scientists from Jülich, Garching and beyondthe opportunity to grow thin film systems for neutron and x-ray experiments.
