    Recently, a newly discovered infinite layer RENiO2 has the potential to exhibit a superconducting transition temperature higher than that of cuprate superconductors. In this study, we have succeeded in fabricating the parent material RENiOy thin film on single crystal substrate by TFA-MOD method. Although the superconducting transition was not observed, the reduction process gave the semiconducting to metallic properties. RENiOy thin films were fabricated on BaxSr1-xTiO3 buffer layers with various Ba/Sr compositions. enabling the application of strain to the RENiOy thin films. RENiOy thin films were epitaxially grown on BaxSr1-xTiO3 buffer layers.
