(a) The X-ray diffraction patterns for polycrystalline In-doped Ba(Zn0.97–xCo0.03In\(_{x}\))2As2 (x = 0.01, 0.02, 0.03 and 0.04) and Cu-doped Ba(Zn0.97–xCo0.03Cu\(_{x}\))2As2 (x = 0.015 and 0.03). (b) The crystal structure of BaZn2As2 with high-temperature tetragonal phase. (c) The Rietveld refinement of Ba(Zn\(_{0.95}\)Co0.03In\(_{0.02}\))2As2. (d) The lattice parameters a and c obtained from the Rietveld refinements for both In-doped and Cu-doped samples.
