The effect of TlF3 substitution on the weak links behaviour and AC susceptibility of Bi1. 8− xTlxPb0. 35Sr2Ca2Cu3OyF3x superconductors
We have studied the thallium fluoride (TlF 3) doping and AC field dependence of the weak
links behaviour and AC susceptibility of Bi 1.8− x Tl x Pb 0.35 Sr 2 Ca 2 Cu 3 O y F 3x
superconductors with range of x= 0, 0.05, 0.10 and 0.15. The estimated value of the peak
temperature (T p) from the derivative of the resistivity curve (dρ/dT) is increased with TlF 3
doping at 0 and 0.5 teslaand attest on both intragranular and weak links transition, while the
full width at half maximum (FWHM) value is decreased. The susceptibility measurements …
