نانو فيلامانها (CNF& CNT) و تركيب ابررساناي 123

Nano filaments (CNT & CNF) and 123 systems

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 Jc. We obtained changes in critical temperature Tc, by changing CNT doping amount in Y-123 systems, and Tc have an optimum in 0.3 wt% CNT doping.
