The effect of Mo substituting and W doping on (BiPb) 2 W x Sr 2 Ca 3 Cu 4-y Mo y O 12+& system where x=0, y= 0; x = 0.1, y= 0.0, 0.03, 0.06, 0.09 and 0.12 have been investigated. The superconducting samples prepared by using conventional solid state reaction method. The calcination and sintering temperatures were obtained by using differential thermal analysis technique (TGA). In order to investigate crystal structure properties and determine the phase determination, X-ray powder diffraction (XRD) measurements were performed. The XRD data showed that the Bi-(2223) phase transforms into the Bi-(2212) phase with increasing Mo substituting for Cu. The morphology properties of the samples determined with the scanning electron microscopy (SEM) measurements. The effects of Mo and W substituted on BSCCO system; we have also performed electrical resistivity (R-T) in order to get critical temperatures. From electrical resistivity critical temperature and transition temperature width were both increased with the increasing of Mo content. The alternative current susceptibility measurement (AC) was performed to obtain critical transition temperature and study magnetic properties of the samples.

“…Since the discovery of Bi-based high-temperature superconductors [1], which are among the most promising materials for technological and industrial applications, many experimental studies have been performed [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] in order to improve their critical temperature (Tc), critical current density (Jc), and better understand the structural properties of the system. The BSCCO families can be described by the Bi 2 Sr 2 Ca n-1 Cu n O 2n+4+y general formula, where n=1, 2 and 3.…”

In this study, the effect of Na substitution on the structural, electrical and magnetic properties of Bi 2 Sr 2 Ca 1-x Na x Cu 2 O 8+y superconductor with x=0.0, 0.05, 0.075, 0.1, 0.15, and 0.2 has been investigated. The effects of partial replacement of Na for Ca have been investigated by electrical resistivity (ρ-T), scanning electron microscopy (SEM), X-ray diffraction (XRD), and magnetic characterizations. XRD results have shown that the Bi-(2212) phase is the major one independently of the Na-concentration. SEM results indicate that the microstructure of samples is improved with increasing of Na-contents. From the electrical resistivity measurements it has been found that Tc is slightly higher than 92 K for Na-concentrations up to 0.20. Moreover, this trend is maintained in the magnetic measurements where the hysteresis loops are increased with increasing Na-concentrations. The maximum calculated Jc, using Bean's model, is around 10*10 6 A/cm 2 at 10 K and ∼ 1000 Oe for the 0.075 Na doped samples.

In this study, the effects of Nb substitution on the Bi-based superconducting materials have been investigated. The X-ray diffraction measurement indicated coexistence of Bi-2212, Bi-2223 phases and some impurity phases of CuO, CuNb 2 O 6 , CaNb 2 O 6 , CaCuO 2 , and Sr 5 Nb 5 O 16 . With increasing Nb content, impurity phases consistent with the Nb element appeared in the samples. Also with increasing Nb content, the Bi-2223 phase of samples gradually was decreased and in contrast, the Bi-2212 phase was increased. From the SEM, results have been seen that with increasing of Nb contents, the crystal structure of the samples was slightly changed because of the disrupted grain growth. From the electrical resistivity measurements, it has been found that with increasing of Nb contents, critical temperature decreases and the superconducting transition width (∆T) increases. Estimated critical current density showed that J c decreases with increasing Nb content, as expected.
