Abstract
A novel experimental procedure has been achieved in order to study the anisotropy properties of the new superconducting oxide ceramics. A magnetic field induced anisotropy confirms the drastic role of the orientation of the crystallites on the knee appearance when cooling the granular Y1Ba2Cu3O7−y superconductor below the ‘‘critical temperature’’ Tc. The results are explained through the preferential destruction of two‐dimensional supercurrent paths due to the upper critical field anisotropy.Keywords
