Effect of Adding Ag Nanoparticles onto Magnetic and Structural Properties of BSCCO Superconducting Compound
Bibliographic record
Abstract
Abstract Effect of adding silver nanoparticles on Bi 1.7 Pb 0.3 Sr 2 Ca 2 Cu 3 O 10+δ superconductor phase by solid state reaction technique. It was studied the significant variations in the superconducting, magnetic and structural properties of Bi-2223 phase. Ag NPs concentration of tiny particles varied, (0 - 1,25) % from the total weight mass of the BPSCCO compound were characterized by X-ray diffraction (XRD) and EDX spectrum measurements. It was found that adding Ag nanoparticles to BSCCO was enhanced the (Bi, Pb)-2223 phase formation up to x=1.25 wt%. On the other hand, the low concentrations of Ag nanoparticles of 0.25 wt% retarded the high-T c phase formation and (T c ) measured that had the maximum improvement in Tc for most samples. The surface morphology investigated were examined by SEM, which the grain size increased with an increase Ag NPs, while the grain size examination showed that both the size and number of voids were reduced. Magnetization variance was measured of the samples by M - T curve, where the highest value for x = 1.25 wt%, and it become clear when the magnetic and resistance transition points are close to each other. Moreover, Critical current density ( J c ) characteristic curves were measured at temperature range (2-150) K.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
