Abstract
The electrical transport of a superconducting BSCCO-2223 Ag-sheathed tape is studied as a function of temperature T, current I, and magnetic field H. In a range of current and field, covering two orders of magnitude, the resistance R(T) is described by R = R o exp{−b[(T m −T)/(T −T o )]0.5}, where T o and T m are the limits of the non-ohmic and field dependent behavior. The threshold T o is a decreasing function of I and H, whereas T m depends only on H. The isothermal R(I) and the R(H) trends confirm the previous function, suggesting that, within the examined ranges, the dissipation may be attributed to a process in which the temperature has a prevalent role, whereas I and H change the limits of the process. The experimental data are consistent with a process in which the dynamics of thermally generated vortices is current and field controlled.
