The field and temperature dependence of the magnetic irreversibility Tg(H) of Bi2Sr2Ca1Cu2Oy and YBa2Cu3O7-delta single crystals as well as oriented grain systems was investigated for different orientations of the applied field. The data reveal a clear anisotropy in the irreversibility lines.

Previous attempts to study magnetically the critical current that can flow in the c-direction, i.e. from layer to layer, in YBa2Cu3O7 have been hampered by the severe anisotropy of the material. We report and discuss the results of measurements in which the experimental problems have been overcome.
