Study of the Effect of Adding Ago on Compound Superconducting based Hg

In this research, we Study the Effect of Ago on compound based on mercury at a concentration of x = (0, 0.1,0.2) and the samples were prepared by the state reaction method Solid at sintering temperature (800°C) for 24 hours and a heating rate of (10 ℃ / min). Then the samples were cooled to room temperature at the same heating rate. To Identify the critical temperature, four-probe techniques have been used and the test of resistivity as a function temperature show that all specimens have a metallic behavior. The XRD analysis for all superconductor specimens was found that the crystal structure was tetragonal for all specimens.
