摘要：

We report the measurement of transport critical current densities in a wide variety of high-temperature superconducting (high T(c)) superlattices and thin films. We find that the temperature dependence of the critical current density J(c) for all samples may be collapsed into a single curve through the scaling relation J(c)(t)=J(c)(0)(1-t)1.6, where t=T/T(c)(H,THETA). This scaling relation remains valid in fields of up to 5 T and in all field directions THETA with respect to the c axis of the sample with the field kept perpendicular to the current.
