“…For these purposes, some researchers have attempted to synthesize superconductors by various processing methods and introducing various dopants. The RE-123 samples preparations using the sol-gel method [4], by the melt-textured growth [5], by infiltration-growth technique [6], and by top-seeded melt-growth (TSMG) [7] have so far been reported. Further, microstructure in conjunction with superconducting properties with various doping have also been investigated [8,9].…”

The rare-earth copper oxide superconductors of Nd 1 Ba 2 Cu 3 O 7-G , Nd 0.5 Gd 0.5 Ba 2 Cu 3 O 7-G and Nd 0.33 Eu 0.33 Gd 0.33 Ba 2 Cu 3 O 7-G have successfully been synthesized by introducing a wet-mixing method. Sintering was carried out at varying temperatures of 920, 940, 960 and 970 o C for 10 hours in air. The effects of sintering temperature on the structural and crystallinity of the synthesized powders was studied using X-ray diffraction techniques. Rietveld analyses gave clearly separated diffraction (013) and (110) peaks at respectively 32.2 o and 32.5 o , decreasing Goodness-of-Fit, increasing average crystal size and increasing orthorhombicity with increasing sintering temperature from 920 to 970 o C. In this research, the superconducting critical temperatures of Nd 0.5 Gd 0.5 Ba 2 Cu 3 O 7-G and Nd 0.33 Eu 0.33 Gd 0.33 Ba 2 Cu 3 O 7-G powders sintered at 970 o C and measured using a SQUID magnetometer was obtained to be about 88-91 K.

Superconducting nanofibers have attracted much attention in basic researches and practical applications due to their unique physical properties such as broad phase transition temperature, excellent heat conductivity, and high critical current density, etc. Electrospinning, as a common method to prepare nanofibers, also has many applications for the preparation of superconducting nanofibers. However, a few of the new methods to fabricate superconducting nanofibers via electrospinning still need further investigations. This review firstly introduces several potential electrospinning methods to obtain superconducting nanofibers, then proceeds to summarize the recent progress in the field of electrospun superconducting materials. The preparation process, difficulties and problems, physical properties of the superconducting nanofibers or nanonetworks (such as superconducting transition temperature, critical current density, critical magnetic field strength, fiber morphology, and structure, etc), theoretical analysis of the properties, and the techniques to improve the performance are also reviewed. In addition, some suggestions and prospects for the development and applications of electrospun superconducting materials in the future are discussed.
