The authors report on the chemical, structural, and optical properties of molecular beam epitaxy synthesized thin films of multifunctional Fe2CrO4 on (001)-oriented MgAl2O4 (MAO). Substrate temperatures near 500 °C are required to obtain smooth films with an out-of-plane lattice parameter consistent with the 3.8% compressive strain induced by the film and substrate lattice mismatch. Mg diffusion from the MAO substrate is kinetically suppressed up to 500 °C. They discuss antiphase boundaries in symmetry matched epitaxial systems. Furthermore, this research provides new insight into the epitaxial growth and crystalline properties of crystal symmetry matched Fe2CrO4/MAO(001) heterostructures.
