Abstract
We measured the resistivity of several c-axis-oriented YBCO films unde r 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 ma gnetoresistivity up to 164 K we didn't find any proof of any rising tr end with temperature's increasing of the fluctuating resistivity.
