Irreversibility field and Upper Critical of MWCNT added Single Crystal FeSe0.5Te0.5 Superconductors
Abstract
After it was determined that the electrical conductivity properties of Multi-Wall-Carbon-Nanotubes were quite good, MWCNTs are used as a support material for electrical conductivity in many materials. A similar situation is also possible for superconducting materials, and MWCNTs have recently been used as additives in many superconducting materials. In this study, 2 % and 4 % MWCNT added single crystal FeTeSe materials were produced using the self-flux method. The effect of the MWCNT addition on the electrical conductivity and magnetic properties was investigated. The results obtained show no significant change in the superconducting phase transition temperature but changes both structurally and in terms of Magnetizations and critical current density were obtained. In addition, it was observed that there were changes in the Irreversibility Field and Upper Critical field properties of the FeTe0.5Se0.5 superconducting samples produced.
