Abstract
Oriented (Hg0.7Mo0.3)Sr-2(Ca0.7Y0.3)Cu2Ox and (Hg0.9Re0.1)Ba2CaCu2Oy superc onducting films were prepared on SrTiO3 substrates using laser ablation and post-sg-vapor annealing. Due to the stability of Mo0.3Sr2(Ca0.7Y0.3)Cu2Ox and Re0.1Ba2CaCu2Oy in air, no special handling was needed during the grind ing, mixing and pressing of the precursor targets. The superconductivity of the films was characterized with the temperature dependence of the ac susc eptibility (chi -T) and the resistance (R-T) while the crystallography was probed with x-ray diffraction (XRD) and scanning electron microscopy (SEM).
