“…Nanocomposites exhibit novel optical, electrical, and magnetic properties compared with their pure metal oxide and present possibilities for several technological applications. Nano-sized oxide such as ZnO 4 , MgO, PbO 5 , NiO 6 , and Bi 2 O 3 7 have been added to (Bi,Pb)-2223 and exhibited enhancement in the transport critical current density ( J c ). The size and element of nanoparticles are important to improve in J c .…”

In this work we have tried to prepare Ni and Ag doped ZnO nanopowders using the sol gel technique. The influence of Ni and Ag (1, 3 and 5 mol.%) on the crystalline structure and optical properties of ZnO was investigated. The samples were characterized by XRD, FTIR and UV–visible spectrophotometer. XRD patterns confirmed the wurtzite formation of doped and undoped ZnO nanopowders. The average crystallite sizes of the prepared samples found from XRD were 19 nm for undoped ZnO, from 17 to 22 nm for Ni-ZnO and from 19 to 26 nm for Ag-ZnO. The average crystallite size of Ag-ZnO increased with increasing Ag contents. Different optical properties of Ni-ZnO and Ag-ZnO nanopowders were observed for different Ni and Ag content. The band gaps of Ni-ZnO and Ag-ZnO nanopowders were lower than that of the undoped ZnO (3.1 eV). The band gaps of Ag-ZnO were lower than that of Ni-ZnO. The optical properties of ZnO were enhanced by Ni (mol.%) in the UV region and by Ag (3 and 5 mol.%) in the visible region.

“…The coherence length of Bi-2223 is around 2.9 nm and the penetration depth is between 60 and 1000 nm [9]. Agsheathed Bi-2223 tapes with addition of Bi2O3, PbO, Fe3O4, CoFe2O4, MgO, NiO, Co3O4 and NiF2 nanoparticles within this range were found to have higher Jc compared to pure Bi-2223 tapes [10][11][12][13][14][15][16][17].…”

Effect of complex magnetic oxide Co0.5Ni0.5Fe2O4 (CNFO) nanoparticles addition in (Bi1.6Pb0.4)Sr2Ca2Cu3O10 (Bi-2223) superconductor tapes was investigated. Ultrafine Bi-2223 powder precursor was prepared via co-precipitation method and was added with 0.01 – 0.05 wt.% Co0.5Ni0.5Fe2O4 nanoparticles during the final heating stage. The sample with 0.01 wt.% addition, Bi-2223(CNFO)0.01 was found to have the highest critical current density, Jc. This sample were then chosen to be fabricated into Ag-sheathed superconductor tapes using the powder-in-tube (PIT) method. The tapes were sintered for 50 and 100 h at 845 °C. The phase, microstructure and Jc of the samples were determined by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and four point probe, respectively. Jc of Ag-sheathed Bi-2223(CNFO)0.01 tapes sintered for 100 h was 19830 A/cm2 at 30 K and 3970 A/cm2 at 77 K compared to tapes without addition which showed a much lower Jc(6370 A/cm2 at 30 K). This study showed that CNFO nanoparticles could act as an effective flux pinning centers to enhance the critical current density in the Bi-2223 superconductor.

“…Generally, the major of the studies done so as to augment the superconducting characteristics of BSCCO is the addition or substitution process of the elements to the matrix. Recently, nanoparticle addition or substitution processes to Bi-2223 phase is condensed day by day with the help of the developing technology [20][21][22][23][24][25][26][27][28][29][30]. Additionally, introduction of nanoparticles in the high temperature superconducting systems has attracted significant attention due to the fact that these particles are thought as simply controlled and productive instrument to develop superconducting characteristics.…”

In this study, it is examined the significant variations in the superconducting, electrical and structural belongings of Bi-site Gd nanoparticle substituted Bi-2223 crystal. The Bi2.0-xGdxSr2.0Ca2.1Cu3.2Oy (0≤x≤0.3) materials obtained with the standard solid state reaction technique are characterized by dc resistivity (ρ-T), X-ray diffraction (XRD) and transport critical current density (Jc) measurements. Moreover, all experimental findings as regards room temperature resistivity, residual resistivity, critical transition temperatures (𝑇 𝑐 𝑜𝑛𝑠𝑒𝑡 − 𝑇 𝑐 𝑜𝑓𝑓𝑠𝑒𝑡 ), crystallinity, lattice constant parameters, average crystallite size, phase fraction and strength quality of interaction between superconducting grains in the Bi-2223 ceramics declare that the structural, electrical and superconducting characteristics degrade systematically with the ascending of the Gd substitution level in the Bi-2223 samples. Furthermore, the major reason of the reduction trend observed especially in the electrical and superconducting features is in relation with the hole localization problem in the Cu-O2 layers. In this regard, grain boundary weak connections, dislocations and defects in the matrix considerably ascend with the enhancement of Gd nanoparticle substitution level.As seen from XRD measurements, it is clearly determined that there seems to be a decrement in the Bi-2223 phase with the enhancement of Gd inclusions up to the substitution amount of x=0.1. After this critical point, new characteristics peaks of Gd2O3 appear and measurement findings rapidly diminish to the minimum values. This substitution level emphasizes that the solubility limit of Gd is noted to be x=0.1 for Bi-2223. Likewise, the regular decrement observed c-axis length, critical current density and grain size favors the regular retrogression of the superconducting characteristics.
