| Summary: | Superconducting study present the properties of small weight percent of magnetic nanoparticles Dy2O3 from x = 0.0 to 0.10 added in Bi1.6Pb0.4Sr2Ca2Cu3O10+δ - (Dy2O3)x. It is found, the form size of magnetic nanoparticles Dy2O3 is spherical, Nano Dy2O3 particles will enter easily into the Bi, Pb-2223 superconductor. From here it is early to conclude the inducing of Dy atoms into the Bi, Pb-2223 crystal structure because Bi-based superconductors are known for their strong anistropic properties and extremely short coherence length (ξ) as it is correlation with significant change in it microstructure, lattice parameter and the normal state conductivity of the system. The characterization on critical temperature (Tc) and transport critical current density (Jc) of magnetic nanoparticles Dy2O3 added to enhance the optimum amount levels added. The maximum Tc achieved Tc-(R=0) 109 K (for x = 0.4) as samples respectively compared to the pure samples. This results will discussed directly to the basis properties changes in Bi, Pb-2223 with addition of magnetic nanoparticles of Dy2O3. © (2014) Trans Tech Publications, Switzerland.
