J. Schaf et al., ANISOTROPIC MAGNETIC IRREVERSIBILITY IN SINGLE-CRYSTALS AND ORIENTED GRAIN SYSTEMS OF BI2SR2CA1CU2OY AND YBA2CU3O7-DELTA SUPERCONDUCTORS, Physica. C, Superconductivity, 235, 1994, pp. 2803-2804
The field and temperature dependence of the magnetic irreversibility T
g(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 irreversi
bility lines.
