摘要:

We have achieved ablation of Bi‐Sr‐Ca‐Cu oxide from single targets of superconducting pellets by CO2‐laser pulses of l ms length to grow superconducting thin films. Upon annealing, the 6000‐A˚ thin films have aTc(onset) of 90 K and zero resistance at 78 K. X‐ray diffraction patterns indicate the growth of single‐phase thin films. This technique allows growth of uniform single‐phase superconducting thin films of lateral area greater than 1 cm2.
