摘要：

The transport critical current density J(c) of single-crystal TBa2Cu3O7-delta thin films has been measured in weak magnetic fields applied at varied angles to the film surface. There are samples with the hysteresis of J(c) against H and with no hysteresis. The hysteresis occurs in fields not parallel to the direction of the transport current except near the critical temperature. The presence of the hysteresis is related to the value and the temperature dependence of electrical resistivity.
