Abstract

The Zn-doped ErBa₂Cu₃O_7-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 ₂Cu₃O_7-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 (R_S) measurement revealed that the ErBa₂(Cu_0.9Zn_0.1)₃O _7-δ films showed a superconducting transition temperature (T_C) below 70 K. The R_S value of the ErBa ₂(Cu_0.997Zn_0.003)₃O _7-δ films and that of the ErBa₂(Cu _0.995Zn_0.005)₃O_7-δ films was lower than that of the ErBa₂Cu₃O_7-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 ErBa₂Cu₃O_7-δ films, which showed a low R_S.
