Sažetak (hrvatski)
The magnetoresistance of a (Bi,Pb)_2Sr_2Ca_2Cu_3O_10+y Ag sheathed tape was measured in the temperature range 15 K ≤ T ≤ 120 K and magnetic field B ≤ 15 T applied perpendicular to the broader surface of tape. Throughout the explored field range, the onset of resistivity shows Arrhenius behaviour ρ ∝ exp(-U^*(1-T/T_cs)/kBTB^0.5) where U^* is the sample dependent constant, and T_cs is the temperature somewhat higher than the temperature of the resistivity onset. The observed resistance variation can be attributed to a thermally activated flux flow in a highly viscous vortex-liquid regime characterized by a plastic deformation of vortices. Experimentally determined resistive irreversibility line B_irr vs. T_irr follows the power-law dependence B_irr(T_irr) ∝(T_cs/T_irr-1)^2 which can be derived from the exponential behaviour of resistivity. Our Birr(T_irr) data can also be fitted by the combination of the Josephson coupling model and depinning of pancake vortices. This fit provides very reasonable values for B_c2, B_c1, B_c, ξ_ab and αab of Bi2223 compound, and removes the unphysical divergence of Birr(T-> 0) resulting from the above power-law fit.
