“…It can be concluded that the blossom of the US-SnO2 nanoparticle, from spherical to a huge needle-like cluster, affects negatively the formation of the Bi-2223 phase [21]. The Jc(B) of the samples at 65 K was calculated by the modified Bean model: Jc = 20ΔM/[a(1b/3a)] and presented in Figure 4 [2,5,22]. The contrariant influences were found in the series' two types of SnO2 nanoparticle doping.…”

“…Numerous investigations have been conducted on the Bi2Sr2Can-1CunO2n+4+δ (BSCCO) hightemperature superconductor system since its discovery, aiming to enhance its superconducting properties [1][2][3]. The BSCCO system consists of three distinct superconducting phases, namely Bi-2201 (n = 1), Bi-2212 (n = 2), and Bi-2223 (n = 3), with corresponding critical temperatures (Tc) of 33 K, 80K, and 110 K, respectively [4,5].…”

“…The Bi-Pb-Sr-Ca-Cu-O (BPSCCO) ceramic superconductor has faced challenges related to flux pinning and the enhancement of critical current density (Jc). To address these issues, researchers have explored various techniques and strategies to create artificial pinning centers [2,3,8,9]. In recent studies, the incorporation of nanoparticles into BPSCCO has been investigated as a means to improve Jc and enhance flux pinning capabilities.…”

The effect of additions of two series of SnO2 nanoparticles synthesized using two different methods on crystal structure and superconductivity of Bi1.6Pb0.4Sr2Ca2Cu3O10+δ (BPSCCO) superconductors was investigated. Two series of spherical SnO2 nanoparticles were synthesized independently by using ultra-sonication (US-SnO2) and hydrothermal (HT-SnO2) methods. Polycrystalline samples of (Bi1.6Pb0.4Sr2Ca2Cu3O10+δ)1−x(SnO2)x, where x ranged between 0, 0.002 and 0.004, were fabricated by the solid-state reaction method. X-ray diffraction patterns showed a decrease in the volume fraction of the Bi-2223 and an increase in that of the Bi-2212 phases. Scanning electron microscopy images presented the “needle-like blossom” on the surface of the US-SnO2 doped samples, while the phenomenon was not found on the HT-SnO2 doped samples. The Tc was decreased extremely with US-SnO2 doping while slightly HT-SnO2 nanoparticle-doped samples. The field dependence of Jc, Jc(B), showed the opposite tendencies on two series of samples: Jc(B) was enhanced on the HT-SnO2 nanoparticle-doped samples, and that was decreased on UT-SnO2 nanoparticle-doped samples. The application of the Dew-Hughes model to explore the flux pinning mechanism exhibited that the point-like pinning centers were dominant on the HT-SnO2 doped samples. On US-SnO2 doped samples, however, the additional pinning center type was not found and could be explained by the observed over-sized SnO2 nano-needle.
