Abstract

In this paper, we study the correlation between the depositing oxygen pressure and surface resistance R8 of YBa2Cu3O7-δ (YBCO) films fabricated by pulsed-laser deposition method. It reveals that oxygen pressure has great influence on Rs. In terms of minimum Rs, there exists optimum value of oxygen pressure which is different from the optimum oxygen pressure for maximum Tc. The crystalline orientation and surface morphologies of the films are helpful in understanding the variations of Rs with the oxygen pressure.
