Non-vacuum electrodeposition (ED) was used to prepare simplified Gd 2O3/Gd2Zr2O7 and CeO 2/Gd2Zr2O7 buffer layers on a Ni-W substrate. Post-annealing conditions of electrodeposited precursor films were optimized to obtain high-quality biaxially textured buffer layers. The buffer layers were characterized by X-ray diffraction, optical profiling, and transmission electron microscopy (TEM). The effect of the cap layer thickness on the surface morphology and texture of the buffers was also studied. The microstructure of CeO2/Gd2Zr2O7 was analysed and compared to Gd2O3/Gd2Zr 2O7. The high-resolution TEM shows biaxially textured crystalline elctrodeposited Gd2O3 and CeO2 cap layers on the electrode-posited Gd2Zr2O7 layers without any defects. YBa2Cu3O7-δ (YBCO) superconductor was deposited by pulsed laser deposition (PLD) on the simplified ED-Gd2O3/Gd2Zr2O7 and ED-CeO2/Gd2Zr2O7 buffers. Transport current density of 3.3 MA/cm2 at 77 K was obtained for PLD YBCO deposited on ED-Gd2O3/Gd2Zr2O 7 buffer layers.
