Abstract

We report the fabrication of YBa₂Cu₃O_7−δ (Y-123) superconducting thin film via a liquid-assisted powder deposition technique. Acetone was used as the dispersion medium and partial melting was employed. Two samples were grown at different partial melting temperatures and annealed at varied temperature profiles. From Scanning Electron Microscopy, both samples grown were smooth-textured and have a thickness of about 1 μm. C-axis orientation of the samples was evident from the peaks obtained from the XRD patterns. Superconductivity is verified by resistivity measurements. Sample 1 has a Tc_onset of ≈75 K while Sample 2 has a Tc_onset of ≈90 K.
