dc.description.abstractThe influence of rare earth (RE - Ce, Gd) doping at Nd site in NdFeAsO0.7F0.3 superconductor wherein Ce and Gd are having ionic radii in the order Ce>Nd>Gd is investigated. The structural and superconductivity characterization of the pure and doped samples show that Ce doping enhances the TC of Nd1-xRExFeAsO0.7F0.3 to a maximum of 53.6 K at x=0.1 while Gd doping attains a TC of 55.1 K at x=0.15. Interestingly, both Ce and Gd doping create neither any secondary phases nor precipitates within the detection limit of XRD. However, the lattice defects due to Ce and Gd doping modifies NdFeAsO0.7F0.3 and assists in pinning the flux lines on these defects thereby exhibiting an enhanced JC(H) performance especially at high fields. It is also observed that the relatively smaller ionic size of Gd is more effective in TC enhancement, while the lattice defects due to larger ionic size of Ce favors the remarkable enhancement of JC(H).
