“…Muna et al [8] found that not only the physical properties of HTSc Bi 2−x Cu x Pb 0.3 Sr 2 Ca 2 Cu 3 O 10+δ for Cu (0.1 ≤ x ≤ 0.5) depended greatly on the elemental composition, but also it was very much delicate with the details of the preparation method.…”

Effect of La Doping on the Crystal Structure, Electric, Magnetic and Morphologic Properties of the BSCCO System

“…This suggests that as the dopant content is increased, it allows the formation of the lower T C phases such as Bi-2201 and Bi-2212, and not improve the stability of the Bi-2223 phase. According to Abbas et al 34 , the formation To obtain the lattice parameters, Eq. (2), we assumed an orthorhombic symmetry corresponding to the peaks associated with Bi-2212 in the XRDs 36 :…”

Effect of Preparation and Annealing Temperature on the Properties of (Hg,Tl)-2223 Superconductor

“…This may be due to the reduced oxygen concentration in the bulk that may act as effective channelling centres of oxygen vacancies. 8,9 The values of T c onset and T c offset , which are determined from the electrical resistance behaviour are 111 K and 63 K respectively for S 1 sample, while the T c onset and T c offset for the S 2 sample are 107 K and 93 K, respectively. The transition width ΔTc = T c onset -T c offset determined from the difference between the onset temperature and zero resistance temperature for (Hg,Tl)-2223 samples are listed in Table 1. )…”
