We report on the chemical, structural, and optical properties of molecular beam epitaxy (MBE) synthesized thin films of multifunctional Fe2CrO4 on (001)-oriented MgAl2O4 (MAO). Substrate temperatures near 500 °C are required to obtain smooth films with the expected out-of-plane (OOP) lattice parameter. Mg diffusion from the MAO substrate is kinetically suppressed up to 500 °C. We discuss anti-phase boundaries in symmetry matched epitaxial systems. This research provides new insight into the epitaxial growth and crystalline properties of crystal-symmetry-matched Fe2CrO4/MAO(001) heterostructures.
