چکیده انگلیسی
The temperature and magnetic field dependences of the ac resistance and the critical currents of a c-axis oriented, ab aligned (Tl0.6Pb0.24Bi0.16)(Ba0.1Sr0.9)2Ca2Cu3Oy film on (1Â 0Â 0) single-crystalline lanthanum aluminate substrate were measured and analysed. The magnetic field and the temperature dependences of the width of the resistive transition to the superconducting state and of the irreversibility fields were analysed both within the flux-creep model and the superconducting liquid vortex state model. The temperature width of the resistive transition was explained on the basis of the superconducting Josephson weak links model of resistance and the barrier of vortex motion. The irreversibility field was described by an exponential formula. The temperature dependence of the critical current was described by a power law; the magnetic field dependence of the critical current was fitted to a Kim-type power law as well as to an exponential relation from the percolation model.
