Study of Potassium content and its role in doped superconductor YBa2-xKxCuyO6+x with Rietveld analysis of XRD patterns
Abstract:   (3056 Views)

In this article, we have employed GSAS software to do Reitveld profile refinement on XRD patterns from H-Tc superconductor powder YBa2-xKxCu3O7-y (02. On the other hand, substituting of K instead of Ba led to oxygen depletion and also lowering the Ba (K) plane position along the Z direction (||c). The structural phase ratio of tetragonal to orthorhombic increased and it means that the superconductivity exist even in samples with dominant tetragonal phase.

Keywords: Superconductivity, Structural phase transition, Reitveld refinement
