Doping Dependence Of Magnetic Susceptibility And Electrical Properties Of High Temperature Superconducting Ceramics
It has been well known that Bi-Sr-Ca-Cu-O system has three superconducting phases represented by general formula, Bi2Sr2Can-1CUnOy , referred to as 2201(n= 1,Tc~ 10K), 2212 (n=2, Tc~ 80K), and 2223 (n = 3, Tc~ 11 OK) The role of calcium and copper seem to influence the formation of those phases...

| description |
It has been well known that Bi-Sr-Ca-Cu-O system has three
superconducting phases represented by general formula, Bi2Sr2Can-1CUnOy ,
referred to as 2201(n= 1,Tc~ 10K), 2212 (n=2, Tc~ 80K), and 2223 (n = 3, Tc~
11 OK) The role of calcium and copper seem to influence the formation of those
phases This research work was focussed at the role played by calcium in the
formation of 2223 phase by doping this site with different elements having different
valences and ionic radius Sample of Bi2-xbpxSr2Ca2Cu3O3(x=01 to 06)and Bi2Pb06Sr2Ca2-"MxCu3Oy (M = Ba, Y, V, Zn, Sn with x =0 02 to 0 10) were prepared using the
conventional solid state reaction technique The samples were sintered at 855°C for
150 hours and annealed at 830°C for 30 hours The transport properties of the
samples were measured using four-point probe resistance measurement, magnetic
properties by using ac susceptibility, microstructure by scanning electron |
