abstract

  • We report the successful preparation of 1212 PbSrYCaCuO thin films by laser ablation. The films are grown in situ on (100)LaAlO3 at the relatively low substrate temperature of 610 °C. The starting composition of the target is not that of the superconductor produced. Its composition was choosen to yield the 2213 PbSrYCaCuO phase, but the structural analysis shows a predominantly 1212 film with a small impurity phase. The films are highly oriented and show superconducting transitions with onsets at 90 K and zero resistance by 75 K.
