Abstract

We have studied the ac response of Sn doped Cu0.5Tl0.5Ba2Ca2Cu3−x Sn x O10−δ superconductor samples from their ac-susceptibility measurements under different magnitudes of ac magnetic fields; H ac=0.4, 4, 16 A/m. The samples with x=0.5 and 1.0 have shown strong flux pinning and intergrain coupling. However, the sample with Sn doping of x=1.5 has shown very poor flux pinning characteristics.
