The temperature dependence of the critical current density of single-crystal films of the high-temperature superconductors has been studied in parallel with the contactless (magnetic) methods and contact methods. The Bean model is shown to work well in magnetic fields up to 102 Oe, which are oriented perpendicular to the film plane.
