What is Comparative study of dimensionality and superconducting parameters in YBCO–NaNbO3 nanoparticles- and nanorods-added composite sample from excess conductivity analysis about?

Excess conductivity and dimensional fluctuation effects on the superconducting parameters with the addition of nanoparticles (NPs) or nanorods (NRs) of NaNbO 3 in polycrystalline YBa 2 Cu 3 O 7-δ (YBCO) have been studied. Two series of samples were synthesized by solid-state reaction route on addition of 0.5 wt% to 2.0 wt% NaNbO 3 NPs or NRs in pure YBCO superconductor. X-ray diffraction results show the unaffected orthorhombic crystal structure for all the synthesized samples. The field emission scanning electron microscope and high-resolution transmission electron microscope images reflect the addition of NPs or NRs in the YBCO material and indicate that the higher wt% of additive material leads to agglomeration of NPs or NRs. Using the Aslamazov-Larkin model, the fluctuation conductivity and the superconducting parameters such as coherence lengths, critical magnetic fields (B C1 (0) and B C2 (0)), effective layer thickness (d) and critical current densities (J C ) have been estimated. It has been observed that 0.5 wt% concentration of addition of NaNbO 3 NPs or NRs in YBCO compound shows significant enhancement in B C1 (0), B C2 (0) and J C (0), whereas a further increase in add
