Abstract

Undoped and fluorine-doped materials of GdBa₂Cu₃O_7-XF_x (with x = O, 0.05, 0.1 and 0.2) were prepared at high temperature (950° C) by solid state reaction followed by oxygen treatment. X-ray diffractograms of the undoped sample showed single orthorhombic phase. Resistivity measurements showed that T_c(0) decreases with fluorine concentration. Thermopower measurements indicated a peak just before the onset of the superconducting transition. The reasons for the decrease of T_c and the anomalous behaviour of thermopower have been explained.
