The magnitude and anisotropy of the critical current density J(c) as well as the irreversibility field H-irr of BaZrO3 (BZO)-doped YBa2Cu3O7-x (YBCO) thin films are determined by both the amount of BZO and the deposition temperature. The influence of these two parameters was investigated on BZO/YBCO quasi-multilayers in two temperature series with different doping amounts (4 and 9 vol% BZO). The deposition temperature was varied between 790 and 850 degrees C. The samples show an increase in Hirr, logarithmic peaks in J(c)
