Research ArticleOpen accessIn the keywordsFormation of Tl-1212 Phase in CR Substituted (Tl1-xCrx) Sr2CaCu2O7 SuperconductorRanjbar G.M., R. Abd-ShulorSuperconducting samples of (Tl1-xCrx) Sr2CaCu2O7 for x = 0.0-0.7 have been prepared by a solid state reaction technique at normal pressure using high purity elements. The powder X-ray diffraction patterns have been studied for samples. All samples showed the Tl-1212 as the major phase and Tl-1201 as the minor phase. The superconducting transition temperature Tc has been determined from the … …Physics International, Vol. 3, Issue 2 · 20 May 2013 · 6,694 accessesView PDFCite
