✦ Synopsis

We have found noticeable hysteretic behavior in the dependence of the zero-resistance critical temperature obtained through resistivity (p) vs. temperature (T) measurements with applied field (He) in YBa2Cu3OT_~ ceramic superconductors. This behavior is qualitatively explained based on the analogy between the present phenomenon and the analogous hysteresis observed in the transport critical current (Jc) vs. He curves of these materials.
