SYNTHESIS AND CHARACTERIZATION OF HIGH TEMPERATURE SUPERCONDUCTOR

Abstract

We have successfully investigated the phase-purity of YBCO superconducting sample using X-Ray diffraction pattern. YBCO superconducting sample is synthesised by solid state route method We have also analysed the effects of sulphur in FeTe0.60Se0.40-xSx samples and the transport properties of FeTe0.60Se0.40 xSx for different values of magnetic fields at different values of x have been investigated. The resistance versus temperature measurements shows that superconductivity at 14 Kelvin. The temperature dependent resistance measurement has been done by four probe methods.
