We report a general scaling behavior of the dependence of the critical current density jc(B,T,?) on the direction of the magnetic field at low temperatures in c-axis-oriented high-Tc superconductor thin films with different strengths of interlayer coupling. Measurements of jc(B,T,?) for pure YBa2Cu3O7, doped YBa2(Cu1-xZnx)3O7, Bi2Sr2CaCu2O8, and YBa2Cu3O7/PrBa2Cu3O7 superlattice films with different relative orientations of the current j, magnetic field B, and crystallographic direction c all...We report a general scaling behavior of the dependence of the critical current density jc(B,T,?) on the direction of the magnetic field at low temperatures in c-axis-oriented high-Tc superconductor thin films with different strengths of interlayer coupling.
