This comprehensive survey deals with the melt-growth process and characterization of the
novel class of ternary materials,(Nd, Sm, Gd) Ba 2 Cu 3 O y'NSG-123'. Microstructure …

While non-superconducting particles are known to serve as effective pinning centres in
conventional superconductors, their effect in high T c superconductors is still controversial …

Melt processing is the most prominent method utilized in the fabrication of bulk YBa 2 Cu 3 O
x (123) because of the superior transport and magnetic properties of this material. Due to the …

We present a study of flux pinning by in-plane partial dislocations in melt-textured grown
YBa 2 Cu 3 O 7/Y 2 BaCuO 5 (123/211). The in-plane dislocations are generated by high …

Most of the potential applications of the high-temperature superconductors require large
critical currents, much higher than those obtained using a classical sintering process. This …

High critical current density is essential for most large-scale applications of high-temperature
superconductors (HTSs). In addition to the weak link problem, weak flux pinning is a major …

Abstract YBa 2 Cu 3 O 7− χ (123) pellets doped with 0.5 wt.% of PtO 2· H 2 O were melt
textured to determine the effects of PtO 2 additions on the microstructure of melt textured …

Segregation of second-phase particles within Y1Ba2Cu3O7− y domain was investigated in
melt-textured Y-Ba-Cu-O with metal oxide (CeO2, SnO2, and ZrO2) addition. It is found that …
