Abstract

Epitaxial c-axis-orientated HgBa₂CaCu₂O₆ (Hg-1212) superconducting thin films with their dimensions as large as 1/2 inch× 1/2 inch have been recently achieved using a cation-exchange process. Uniformity of the film was studied by slicing samples into eight pieces, on which uniform zero-resistance T_c values above 120 K were observed. In self-field, J_c values of the film range from 14.6×10⁶ to 23.7×10⁶ A cm^-2 at 5 K, 1.77×10⁶ to 3.85×10⁶ A cm^-2 at 77 K and 0.54×10⁶ to 1.38×10⁶ A cm^-2 at 100 K. The scattering of J_c is found to be within 44% across the film and could be smaller with improvement of processing.
