Effect of doping by low content of yttrium at Ca and Sr sites of Bi(Pb)-2212 superconducting ceramics
In this work, a comparative study of the effect of doping bylaw content of Y3+ between (Ca site) and out of (Sr site) the CuO2 planes of Bi(Pb)-2212 phase is presented. Ceramics of Bi1.6Pb0.4Sr2Ca1-xYxCu2O8+d (called CY ...
Effect of Eu doping on structural and magneto-electrical properties of La0.7Ca0.3MnO3 manganites
(Elsevier Science Sa, 2011)
We have investigated the influence of europium (Eu) doping on structural and magneto-electrical properties of La0.7Ca0.3MnO3 compounds. In order to analyze the physical mechanism of a spin disorder system and study their ...
Effect of Re doping on structure and magneto-electrical properties of La1.2Re0.2Ca1.6Mn2O7 manganites
In this paper, the structural and magneto-electrical properties of the double layered La12Re0.2Ca1.6Mn2O7 manganites doped with Re=La, Pr, Eu, Y and Gd are presented. The results show that the decreasing of the ionic radii ...
Structural and electrical properties of cerium doped Bi(Pb)-2212 phases
In this work, a comparative study on the effect of doping by low content cerium at Ca site of Bi(Pb)-2212 phases is presented. Superconducting ceramics of nominal compositions Bi2Sr2Ca1-xCexCu2O8+delta (called CC series) ...
Improvement of superconducting properties of (Bi, Pb)-2223phase by TlF3 doping
(Elsevier Science Bv, 2016)
In this work, the superconducting properties of thallium fluoride (TlF3)doped Bi1.8-xTlxPb0.35Sr2Ca2Cu3 OyF3x(x=0-0.15)compounds are presented. The X-ray diffraction analysis shows that the proportion of (Bi, Pb)-2223phase ...
