Effects of Nb substitution at Cu site on superconductivity and structural properties of TI₀.₉Cr₀.₁Sr₂Ca₀.₉₅Ge₀.₀₅Cu₂₋ᵪNbᵪ*0₇-δ (x = 0 - 0.2) superconductors / Muliana Ismail
The effects of Cu substitution by Nb on superconductivity and structural properties of Tlo.9Cro.iSr2Ca0.95Geo.o5Cu2-JNbJ07^ (x= 0 - 0.2) were investigated. The sample was prepared by using conventional solid-state synthesis method with different concentration of Niobium (Nb = 0, 0.05, 0.1, 0.15, 0.2...
