Material Specification for Y:123; [Y-Ba(Sr)-Cu-O]
Process: Laser Ablation
Notes: "... targets employed in the present experiments were stoichiometric with respect to the metal ions and they contained several phases. These targets have been prepared from mixtures of Y2O3, BaCO3, SrCO3 and CuO using the standard solid-state reaction. The starting materials had a purity of higher than 99.9%. After one hour of mixing and grinding in an automatic ball mill, the corresponding powder was pressed into pellets and calcinated at 900 °C for 24 h. After regrinding and repressing, the pellets were subjected to a second calcination step at 920 °C for 24 h, followed by slow cooling in an O2 atmosphere. The fabrication of the... films by pulsed-laser deposition was performed by means of 248 nm KrF excimer-laser radiation (Φ=4 J/cm2, γ1=20 ns, 10 pulses per second) in oxygen atmosphere (pO2)=40 Pa). Films with a thickness of about 3000 σ have been produced with, typically, 9000 laser pulses... The substrates employed were (100) MgO and (100) SrTiO3."
