Contradictory reports about the electronic and magnetic behavior of bulk Nd0.5Ba0.5MnO3 with uniform disorder exist in the literature. In this work, we investigated single crystalline, A-site disordered thin films of Nd0.5Ba0.5MnO3, grown on the SrTiO3 substrate by pulsed laser deposition. The epitaxial growth of these films in the layer-by-layer fashion has been confirmed by in situ reflection high energy electron diffraction, atomic force microscopy, x-ray reflectivity, and x-ray diffraction measurements. Interestingly, these films are found to be electrically insulating and exhibit spin-glass behavior at low temperatures. This offers a distinct approach to study Ba based half-doped manganites and an opportunity to further manipulate competing charge/orbital ordering and ferromagnetism in such systems, through heterostructure engineering. © 2022 Author(s).
