Data from the synthesis and characterization of a BaTiO3 thin film grown on a GdScO3 (110) substrate, performed in the PARADIM Thin Film Facility. The data includes in-situ RHEED images, atomic force microscopy (AFM) images of the film surface, an theta-2theta x-ray diffraction scan, an asymmetric reciprocal space map taken at the GdScO3 332 Bragg peak, and omega rocking scans taken at both the BaTiO3 002 and GdScO3 220 Bragg peaks.
