Abstract We present a study of the temperature dependence of the critical currentJ c of several dc magnetron sputtered thin Y-Ba-Cu-O films on single crystalline SrTiO3, ZrO2 and Al2O3 substrates. Near the critical temperature Tc it is found thatJ c∼(1–T/Tc)n withn=3 for the SrTiO3 and ZrO2 substrates, whilen=1·3 for the Al2O3 substrate. The temperature dependence in our samples approximately agrees with standard theories for weak links or with the Ambegaokar-Baratoff equation.
