In order to improve the surface quality of the pulsed laser deposited YBCO thin films an off-axis deposition geometry is proposed. Using this new PLD geometry, YBCO thin films have been grown on SrTiO3 substrates. These films were found to have a good surface morphology without droplets or other particulates, and good superconducting and structural properties. We have obtained Tc(R=0)=89 K, R(300)/R(100)=2.6, ΔT=1.5 K, Jc=2×106 A/cm2 (at 77 K and zero magnetic field), and the FWHM of the rocking curve of (005) YBCO peak is about 0.12°. A study regarding the influence of the deposition parameters on the film quality is also presented. © 1997 IEEE.
