Abstract

We have investigated the microstructures of electrodeposited Gd₂O₃ (GO) and Gd₂Zr₂O₇ (GZO) buffer layers for YBa₂Cu₃O_7-δ (YBCO) superconductors with conventional transmission electron microscopy (TEM). A high density of nanoscale voids was present in the GZO buffer layers. No voids were observed in GO buffer layers grown on GZO. YBCO superconductor grown on the GO/GZO buffer layer structure produced a critical current density (J_c) of 3.3 × 10⁶ A/cm² at 77 K in zero field.
