摘要:
We have studied the electrical properties of high-T-c superconductor YBa2Cu3O7 - x films obtained by the ion-plasma deposition technique on sapphire substrates. Dependences of the surface resistance and the critical current density on the film thickness are determined. (C) 2003 MAIK "Nauka / Interperiodica".
