Zl. Xiao et al., Preparation and characterization of (Hg0.7Mo0.3)Sr-2(Ca0.7Y0.3)Cu2Ox and (Hg0.9Re0.1)Ba2CaCu2Oy superconducting films by laser ablation, PHYSICA C, 341, 2000, pp. 2393-2394
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).
