ABSTRACT
We report the improvement of superconducting properties on substitution of Cr in excess at the Fe site in FeCrxSe and FeCrxSe0.5Te0.5. In the case of FeCrxSe, there is an increase in superconducting transition temperature (Tc) by ∼40% with a concomitant increase in the superconducting volume fraction upon 2% excess substitution of Cr. In the case FeCrxSe0.5Te0.5, there is an enhancement in superconducting volume fraction with negligible changes in Tc.
