Abstract

We report the effects of doping Manganese (Mn) on phase evolution and superconducting properties of Bi₂Sr₂CaCu₂O_8+δ. X-ray diffraction shows that at low Mn doping levels, Mn is successfully incorporated in the Sr-site of Bi-2212. However at higher concentration secondary phases start to appear indicating impurities related to Mn compounds. The critical temperature increases with Mn doping however further addition results into decreasing critical temperature. Also a second transition temperature appear at higher concentration (x=0.3) and further addition results into non-superconducting samples.
