摘要：

Magnetic measurements have been made of the anisotropy of the irreversibility field in YBa2Cu3O7 single crystals. Care has been taken to eliminate any contribution from currents circulating in the ab plane to the magnetisation measured with the applied field closely parallel to these planes. Not only do the results demonstrate that persistent currents can flow in the c-direction, but they show also that at a given temperature the irreversibility field is about a factor of 4 higher for B parallel-to ab than B parallel-to c. This magnitude of anisotropy is similar to that in B(c2).
