It is observed that Mn-substitution improved the bulk superconducting properties of FeSe0.5Te0.5 considerably by increasing the superconducting transition temperatures determined from both resistive and magnetic transitions. Our results reveal that x = 0.05 Mn-substituted sample yields the most appropriate superconducting performance, considering all the samples employed. The corresponding value is computed to be 4.7 x 10(4) A/cm(2) for x = 0.05 sample at 8 K under 0.2 kOe, and it decreases to the values 2.54 x 10(4) A/cm(2) and 1.34 x 10(4) A/cm(2) for the x = 0.01 and x = 0.1 samples, respectively.eninfo:eu-repo/semantics/closedAccessPhysical-PropertiesPhase-DiagramBeta-FeseCoLaSeArticle7193285329210.1007/s11837-019-03651-02-s2.0-85068877330Q2WOS:000480790100045Q2
