Abstract: The in-plane normal-state transport properties of electron-doped superconductor (La2-xCex)CuO4 (LCCO) thin films with 0.06 <= x <= 0.17 are studied in magnetic fields up to 40 Tesla. For the whole doping region investigated, the negative magnetoresistivity (n-MR) is found below certain temperatures, with minimum n-MR near the optimal doping (0.10-0.11). In the superconducting region (x=0.09-0.17), all the LCCO films show crossover from positive MR to n-MR. For x=0.09, the magnetic field corresponding to the crossover from positive MR to n-MR shows a parabolic behavior with varying temperature. For x=0.12, second crossing point of rho(B, T) curves is observed by tuning the magnetic field.
