Subsolidus phase relation, crystal structure and superconductivity of the SmBa2-xSrxCu3O7-δ system
Description
The SmBa2-xSrxCu3O7-δ solid solution was investigated by means of X-ray powder diffraction in combination with the Rietveld refinement method. The Sr-doped Sm123 single phase could be synthesized at 950 deg. C in flowing O2. The solubility range of the SmBa2-xSrxCu3O7-δ solid solution is 0.0≤x≤0.9. The structure of SmBa2-xSrxCu3O7-δ is orthorhombic in the range 0.0≤x<0.5, and tetragonal for 0.5≤x≤0.9. The electrical resistivity and the AC susceptibility as function of the temperature for samples with x=0-0.9 were measured. All the samples with 0.0≤x≤0.9 show superconducting properties (TC(onset)=93.9-78.9 K). The TC value of SmBa2-xSrxCu3O7-δ decreases regularly with increasing Sr content
