Superconducting fluctuation of the YBCO films

We measured the resistivity of several c-axis-oriented YBCO films under the magnetic fields, the temperature ranged up to ln(T c/T) = 0.68 and magnetic field up to 7 T. By fitting the data to the Aslamazov-Larkin (A-L) and Maki-Thompson (M-T) terms of the fluctuation contribution, we got reasonable...

Description
Summary:We measured the resistivity of several c-axis-oriented YBCO films under the magnetic fields, the temperature ranged up to ln(T c/T) = 0.68 and magnetic field up to 7 T. By fitting the data to the Aslamazov-Larkin (A-L) and Maki-Thompson (M-T) terms of the fluctuation contribution, we got reasonable parameters' value in the theory. By measuring the magnetoresistivity up to 164 K we didn't find any proof of any rising trend with temperature's increasing of the fluctuating resistivity.
