Abstract

The Zn-doped ErBa2Cu3O7-δ thin films were prepared by a pulse laser deposition (PLD) on a SrTiO3, which is a lattice, matched substrate. The various contents of the Zn-doped ErBa 2Cu3O7-δ ceramics were used as the targets. All the films were grown at 750 °C under an oxygen pressure of 400 mTorr. From the X-ray diffraction (XRD) patterns, only the 0 0 l reflections were observed. Surface resistance (RS) measurement revealed that the ErBa2(Cu0.9Zn0.1)3O 7-δ films showed a superconducting transition temperature (TC) below 70 K. The RS value of the ErBa 2(Cu0.997Zn0.003)3O 7-δ films and that of the ErBa2(Cu 0.995Zn0.005)3O7-δ films was lower than that of the ErBa2Cu3O7-δ films for wide temperature region of 10-90 K. From the observation of the atomic force microscopy (AFM), a lot of pores were observed in the surface of the Zn-doped ErBa2Cu3O7-δ films, which showed a low RS.
