The oxide La1-xPrxMnO3 (x=0.1, 0.2) thin film s howing colossal magnetoresistance has been epitaxially grown on (100) SrTiO 3 single-crystal substrate by pulsed-laser deposition. The films have a pe rovskite structure and perform the colossal magnetoresistance effect with the ma ximum magnetoresistance ratio of 95% under the magnetic field of 5 T. The valenc e of Pr is confirmed as +4 through XPS. Therefore the epitaxial film is most lik ely an electron-doped colossal magnetoresistance fihn.
