FTIR spectroscopy showed that our final samples are totally free of organic elements. Le Bail refinement revealed that they were crystallized in the Bi-2212 phase. A small amount of the omnipresent Bi-2201 phase appeared as an impurity phase in all samples, whereas a small amount of Bi-2223 appeared only in the case ofx = 0.5. In one hand, the Sm doping decreases the cell parameters, and in other hand, it leads to a transformation into a pseudo-tetragonal structure in the case ofx = 0.10.The modulation was found to be incommensurate and increases with Sm content. The magneto-electrical resistivity curves show a transition to the superconductor state. The critical temperature T(C)decreases with the Sm doping, whereas the activation energy U(0)increased from 53.4 meV to 68.9 meV.eninfo:eu-repo/semantics/closedAccessHigh T(c)superconductorsSamarium DopingMagneto-resistivityPechini MethodArticle10.1007/s10948-020-05599-83311332133312-s2.0-85087957974Q3WOS:000548797600001Q4
