A series of studies has been carried out on thin films which were prepared by pulsed laser deposition from micro-grained targets of Y(1-x)Pr(x)Ba(2)Cu(3)O(7-delta) (Y(1-x)Pr(x)BCO) to determine the doping effect of Pr (at Y site) in concentrations between x = 0 - 0.20. Earlier results on bulk materials show that the Pr substitution can significantly enhance the value of J(c)(B) at cost of T(c). Our X-ray diffraction results confirmed the good quality of the films without any impurity phases. Magnetometric studies show the systematic decrease of J(c)(B) when the Pr concentration is increased.
