We report successful preparation of thin films of Y1Ba2Cu3O7−&dgr;(YBC) using the technique of laser ablation on single crystal (001) SrTiO3. X‐ray diffraction (XRD) pattern of the as deposited film showed thec‐axis to be perpendicular to the substrate. The critical current was estimated to be 9×106A/cm2(H∥c) and 4×108A/cm2(H⊥c) at 12K as determined from magnetic hysteresis measurements. Intial base pressure in addition to oxygen pressure and substrate temperture is found to be important to achieve correct stoichiometry and high critical currents.
