摘要：

Indicator ferrimagnetic films with in-plane anisotropy are applied for studying the magnetic flux distribution in high-T(c) YBaCuO (YBa2Cu3O7) single crystals. Induction gradients are measured to estimate the critical current density J(c). Temperature dependences of J(c) are found to be different for different field directions. For the field along the orthorhombic c-axis J(c) parallel-to ab exhibits an exponential temperature decay. In the case of H parallel-to ab, however, J(c) parallel-to ab is changed just a little up to 70 K and then drops sharply near T(c).
