Abstract
An approach to synthesis a novel high-temperature superconductor, Y2Ba5Cu7O x , is presented. The synthes is method was based on the standard solid-state reaction at ambient pressure. The structural parameters and space group were studied using the X-ray diffraction (XRD) technique and the experimental results were refined by the Rietveld method. The XRD results show that the major phases include peaks corresponding to Y123 and Y124 structures with minor shifts as well as a few small peaks representing BaCuO 3 as an impurity. The electrical transport properties of the sample were investigated in the 60–300 K temperature range in the presence of magnetic fields up to 15 kOe. The electrical resistivity of the synthesized compound shows a transition to a superconducting state at $T_{c}^{on}$ = 98 K and zero resistivity at $T_{c}^{off}$ = 92 K which are higher than those of YBa 2Cu 3O7−δ and comparable to the transition temperatures of Y 3Ba 5Cu 8O y . Application of a magnetic field leads to broadening of the tail part of the resistivity versus temperature plots in the mixed states and causes a reduction in $T_{c}^{offset}$ .
