✦ Synopsis

The influence of oxygen concentration on the irreversibility line and critical current of polycrystalline YBa2Cu3Ox was determined using field and zero-field cooled magnetic measurements and magnetic hysteresis data. Although the field dependence of T~=(H) is unchanged, the irreversibility line shifts to lower temperatures for decreasing oxygen content and the critical current density is strongly reduced.

The critical current density Jc of YBazCu30 x epitaxial film as a function of the angle 0 between magnetic field and ab-plane with H \_1\_ I and temperature was measured in various magnetic fields. Maxima of Jc were observed near 0 Β° and 90 Β°, respectively, with that for the latter higher than that
