“…Figures 1 and 2 indicate that as Ni concentration grew, so did peak intensities. The highest peak intensities are found only in the high (Tc) phase (Bi-2223), indicating that the high-Tc phase now constitutes a larger fraction of the material [24,25]. The high Tc (Bi-2223) peak increased with increasing Ni content across the board.…”

Partial compensation Ni2O3 nanoparticles have been considered in relation to their effects on the structure, electric, morphology, and composition of Bi-2223. X-ray diffraction was used to quantify structural characteristics, and the results showed that all of the crystals in the samples are orthorhombic, with the ratio at which the Bi-2223 phase develops increasing The constancy of the lattice along the c-axis was observed. The trend that has been observed suggests that there is a direct proportionality between the concentration of Ni2O3 and the magnitude of the increase. Suggestive of a high-temperature superconductor (Bi2Sr2-xYxCa2Cu3-yNiyO10+δ) composition, where y=0=0.03=0.12 Thanks to 3D AFM, the morphology of the surface has been thoroughly studied. The test specimens showed good crystalline structure and a smooth, uniform surface. We measured Tc with 4 separate probes. The maximum temperature constant (Tc) was measured to be 143 K at y=0.12.

“…The doped ions may change the spacing between CuO layers, afecting the charge transfer to CuO layers. The hole transfer from Cu planes to Bi-O bonds leads to the contraction of Bi-O layers, causing a decrease in c-axis [20].…”

Bu çalışmada nano-Y2O3 ilavesinin Bi-2223 süperiletken sisteminin yapısal, süperiletken, manyetik ve mekanik özellikleri üzerindeki etkileri araştırılmıştır. Bi1.8Pb0.4Sr2Ca 2Cu3O10 + δ + (Y2O3) ile ( x; ağırlıkça % 0,0-0,2-0,4-0,8-1,0) genel formülüne sahip polikristal örnekler katıhal reaksiyon yöntemiyle hazırlandı. Örneklerin yapısal karakterizasyonları için X-ışını kırınımı (XRD), Taramalı Elektron mikroskobu (SEM), Enerji dağılımlı X-ışını spektroskopisi (EDX) ölçümü, Titreşimli numune ölçümü (VSM), Direnç-sıcaklık (ρ-T) ölçümü ve Vickers mikrosertlik ölçümü (VHM) yapılmıştır. XRD desenleri, örneklerde hem Bi -2223 hem de Bi2212 fazlarının bir arada bulunduğunu gösterdi. Nano-Y ilavesinin artmasıyla a örgü parametresi artarken, c örgü parametresi azalmıştır. SEM fotoğraflarında tüm örneklerde tanecik yapısının plaka benzeri olduğu görülmekte ve katkı miktarındaki artmasıyla tabakalı yapı üzerinde nokta şeklinde partiküllerin varlığı daha net görülmektedir. ρ-T ölçümünden hesaplanan delik konsantrasyonu değerleri 0,113 ile 0,160 arasında değişmektedir. Nano-Y miktarı artarken kritik geçiş sıcaklıkları azalmıştır. VSM sonuçları Nano-Y eklenmesiyle kritik akım yoğunluğu değerlerinin arttığını göstermektedir. VHM sonuçları, sertlik değerinin x= % 0,4 katkılı örneğe kadar arttığını ve bu değerden sonra azaldığını göstermiştir.

“…For example, the addition of Sm 2 O 3 nanoparticles improved electrical transport properties of Bi2223 at very low doping levels. 10 The addition of small amounts of Nb improved the Bi2223 grain boundary connectivity, resulting in better superconductivity of the BSCCO system. 11 In addition, the substitution of rare earth ions is an effective means to improve the superconducting transition temperature and critical current density by adjusting the phase structure and microstructure.…”
