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 ยฐ and 90 ยฐ, respectively, with that for the latter higher than that

The effect of different doses of ฮณ-rays on the behavior of the critical current density, J c in an YBa 2 Cu 3 O 7 polycrystalline sample has been investigated at high temperatures. The samples were irradiated at room temperature by a 60 Co ฮณ-ray source at a dose rate of 0.5 MR/h. J c was found to in
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 shif
