Study of Structural and Transport Property of Yttrium based Cuprate and Fe- based superconductors

Abstract

In the present project work, we have reviewed literature related to Y-based cuprate and Fe-based superconductors. We have studied iron-chalcogenides (Fe with Te and Se) and the effect of Co doping on the superconducting properties of iron chalcogenides Fe1.01-xCoxTe0.52Se0.48 polycrystalline samples based on the available magnetotransport measurements data. The temperature dependent resistivity measurements show that the superconducting transition temperature (TC) decreases with the increasing doping concentration of Co. From the magnetoresistance data, the variation of upper critical field HC2 with temperature has been determined.
