“…Also, there is not any change in the position of the peaks, indicating that BaSnO 3 nanoparticles do not enter the lattice. Similar results of unchanged peak positions and undetected nanoparticle-rich phases were obtained by adding ZrO 2 [7], Al 2 O 3 [8], and SnO 2 [9,38] nanoparticles into BiPb-2223 phase. The relative volume fraction values of BiPb-2223, BiPb-2212, and Ca 2 PbO 4 phases are calculated from the following equations, respectively, and listed in Table 1 [8].…”

“…However, its decrease with x ≥ 0.75 wt% could be due to the ability of solid BaSnO 3 nanoparticles to prevent the spatial growth of BiPb-2223 phase. Similar behavior of the relative volume fraction for BiPb-2223 phase was obtained with the addition of different nanoparticles [9,11,38]. The lattice parameters a and c, calculated by using the least-squares method, are listed in Table 1 versus BaSnO 3 nanoparticle addition.…”

Co-precipitation method and conventional solid-state reaction technique were used to synthesize BaSnO 3 nanoparticles and (BaSnO 3 ) x /Bi 1.6 Pb 0.4 Sr 2 Ca 2 Cu 3 O 10+δ (0 ≤ x ≤ 1.50 wt%) samples, respectively. X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and electrical resistivity data were used to characterize BiPb-2223 phase added by BaSnO 3 nanoparticles. The relative volume fraction and superconducting transition temperature T c of BiPb-2223 phase were enhanced by increasing BaSnO 3 addition up to 0.50 wt%. These parameters were decreased with further increase of x. The resistive transition broadening under different applied DC magnetic fields (0.29-4.40 kG) was analyzed through thermally activated flux creep (TAFC) model and Ambegaokar-Halperin (AH) theory. Improvements of the derived flux pinning energy U, critical current density J c (0) estimated from AH parameter C(B), and upper critical magnetic field c2 (0) B , were recorded by adding BaSnO 3 nanoparticles up to 0.50 wt%, beyond which these parameters were suppressed. The magnetic field dependence of the flux pinning energy and critical current density decreased as a power-law relation, which indicated the single junction sensitivity between the superconducting grains to the applied magnetic field. Furthermore, the increase in the applied magnetic field did not affect the electronic thermal conductivity e  above the superconducting transition temperature and suppressed it below T c .

“…Sejak penemuan superkonduktor suhu tinggi kuprum oksida sistem Bi, banyak kajian telah dijalankan untuk menambah baik ciri bahan ini kerana ia sesuai diaplikasikan dalam teknologi dan industri (Yavuz et al 2016). Antara semua bahan superkonduktor suhu tinggi, sistem Bi(Pb)-Sr-Ca-Cu-O adalah salah satu bahan yang telah dikaji dengan meluas ekoran cirinya yang istimewa untuk aplikasi dalam teknologi masa depan.…”
