Bulk superconductor samples of YBa2Cu3-xCoxO7- with (x= 0.0, 0.1, 0.15 wt %) are synthesized by solid-state reaction method. Both x-ray diffraction (XRD) and electron microscopy have been employed to study the phase identification, dislocations and the local structure of these samples. Transition temperature of the samples has been determined by four probe resistance measurements. The x-ray diffraction patterns indicate that the gross structure of YBa2Cu3-xCoxO7- do not change with the substitution of Co. The zero resistance critical transition temperature (Tc) is found to decrease with the increase concentration of Co in compound.
