“…Similar results were obtained by Mawassi et al[28] and Tanaka et al[29]. No peaks belong to Y 2 O 3 nanoparticles were found in the XRD pattern as the amount of addition is very low, and it was incorporated into the crystal structure.…”

Bi 17 Pb 0.3 Sr 2 Ca 2 Cu 3 O 10+δ superconductor samples were synthesized by the conventional solid-state reaction method. To study the effects of the addition of yttrium nanoparticles to the superconducting system, nano Y 2 O 3 was introduced by small weight percentages (0.2, 0.4, 0.6, 0.8, and 1.0 wt%) in the first step of the synthesis process. Phase identification and microstructural characterization of the samples were investigated using X-ray diffraction and scanning electronic microscopy (SEM). Energydispersive X-ray spectroscopy (EDX) analysis was utilized to confirm the presence of the desired elements in the chemical composition of the samples. Moreover, DC electrical resistivity as a function of the temperature, critical current density (J c ), AC magnetic susceptibility, and DC magnetization measurements were carried to evaluate the relative performance of samples. XRD analysis showed that both (Bi,Pb)-2223 and Bi-2212 phases coexist in the samples having an orthorhombic crystal structure. Both the onset critical temperatures (T c ) (onset) and zero electrical resistivity critical temperatures (T c ) (R = 0) of the samples were determined from the DC electrical resistivity measurements. An improvement of the superconducting transition temperature of 3.0 % was obtained with increasing Y 2 O 3 nanoparticles to x = 1.0 wt%, while the critical current density is improved by 200 %. AC magnetic susceptibility measurement showed that the diamagnetic fraction and intergranular coupling of the x = 1.0 wt% sample are greater than those of the others. The variation of magnetization with temperature (M-T curve) of the samples was measured by cooling the sample in zero fields (ZFC) and an applied field of 10 Oe (FC). The results of AC magnetic susceptibility and DC magnetization measurements were in good agreement with DC electrical resistivity measurement.

“…Other studies which used Gd, Nd and dilute rare-earth doping are shown to repair grain boundaries or improve flux pinning that enhanced superconducting properties [10][11][12][13]. Addition of particle and nanoparticles such as Ag, Dy, Zr, Eu, Nb, Al and Ca-iridates improves grain connectivity [14][15][16][17][18][19][20][21].…”

The effect of In 2 O 3 on grain connectivity and superconducting properties of Bi-2212 was investigated. Indium was intentionally doped on the Sr-site of BSCCO at doping levels from x = 0 to x = 0.8. Accessing the Sr lattice site in BSCCO provides useful control on the possible effect of indium on its superconducting behavior and microstructural properties. Results show that the superconductivity persists in BSCCO even at high indium concentration (x = 0.8). However, secondary phases form at x ≥ 0.4 indium concentration affecting normal resistivity, magnetic susceptibility response and superconducting transition temperature of BSCCO. Formation of secondary phases weakens the diamagnetic intergrain coupling. An apparent increase in the formation of micron-sized grains is related to the increased sinterability of BSCCO with indium doping. The enhanced sinterability of BSCCO with indium provides possibility of synthesizing thin films with reduced thermal heat treatment.

“…W. Abdeen, et al [12] found that increasing the addition of nano-Ag up to x = 1.5 wt% enhanced the phase formation and improved the superconducting transition temperature and the critical current density J c . R. Mawassi et al [13] studied the effect of Ag nanoparticles addition on the superconducting properties of (Bi, Pb)-2223 phase. They found that the electrical and granular properties were greatly enhanced, indicating more efficient pinning mechanisms.…”

The growth of epitaxial Ag nanoparticles doped (Bi, Pb)-2223 thin films on Si (111) substrates by pulsed laser deposition (PLD) and post-deposition oxygen annealing have been achieved. The phase identification and gross structural characteristics of synthesized films explored through X-ray diffractometer reveal that all the samples crystallize in orthorhombic structure. DC electrical resistivity measurements were done by the standard four-probe method and the results showed improvement in T c by increasing Ag nanoparticles to 1.0 wt% which had a maximum enhancement in T c for all investigated films. The surface morphology investigated through scanning electron microscope (SEM) and atomic force microscopy (AFM) results showed that an increase in T c with the appropriate Ag nanoparticles addition in the samples is associated with the enhancement of Bi (Pb)-2223 phase formation.
