Abstract
The effect of oxygen substitution at the selenium site and manganese substitution at the iron site in FeTe0.5Se0.5 superconductor was investigated. It was found that upon partial O substitution, Tc marginally decreases as seen in both resistivity and magnetization experiments. Tc decreases even by a small amount of oxygen concentration (as low as 1 %). This observation is in contrast against an earlier work on Fe(Te/Se) samples,1 wherein Tc as well as superconducting volume fraction were reported to increase in the samples annealed in air. Mn-doping leads to a decrease in Tc in FeTe0.5Se0.5, which one would expect considering pair-breaking due to Mn2+-ions.
