Title: Effect of Ni substitution for Cu in the vortex state of (Bi,Pb):2223 superconductor

Abstract

The influence of the partial substitution of x = 0.02 Ni for Cu on the magnetoresistivity in the (Bi,Pb):2223 superconductor has been investigated. The resistive transitions were studied under magnetic fields up to 0.7 Tesla by using the dp/dT versus T curves. The Arrhenius plots shows that the dissipation processes are induced by two distinct regimes. In the high temperature regime the activation energy is proportional to lnB and to B{sup {minus}1} in low temperature regime. The main dissipation processes in these regimes are discussed.
