Abstract
We successfully synthesized La1.85Sr0.15Cu1-xMxOy (M=Zn,Ni,Mg) with y≤0.30 ceramic cuprates. X-ray diffraction studies show that there is no impurity phase in all Zn,Ni,Mg-doped LSCO. Rietveld refinement technique is used to obtain the lattice constant,atomic position coordinates and reflection profile parameters for all samples. There is a tetragonal-to-orthorhombic phase transition in the range of 0.10c of the samples in superconducting state.
