Nano filaments (CNT & CNF) and 123 systems

Abstract

The effects of carbon nano filaments on the superconducting properties of Y-123 compound were studied. Samples were synthesized using standard solid-state reaction technique by adding CNT up to 1 wt %. The XRD data confirm the single phase orthorhombic structure for all the samples. The SEM of samples shows existence of CNTs which can powered the weak links that increase the . We obtained changes in critical temperature , by changing CNT doping amount in Y-123 systems, and TC have an optimum in 0.3 wt% CNT doping .
