Enhancement of critical current density of (Pb,Sn)-doped Bi-2212 superconductors at high temperature
(2001-06)
The magnetic properties of ceramic samples of Bi(PbSn)SrCaCu O (x = 0,0.1,0.2,0.3 and 0.4) superconductors have been investigated using a vibrating sample magnetometer from 20 to 50 K and up to 8 T. Phase analysis shows ...
