We report on the growth of La 0.8 Ce 0.2 MnO 3 thin films on (0 0 1) LaAlO 3 substrates by pulsed laser deposition. CeO 2 as an impurity is present in both the bulk and film samples. The electrical transport and magnetic properties of the films are similar to that of the divalent cation-doped or La deficient LaMnO 3 , which show colossal magnetoresistance. Thermopower measurements indicate that the carriers are holes. The results are explained in terms of a La site deficiency due to the existence of CeO 2 .
