Oriented, single phase thin films of La_{1-x}Ca_{x}MnO_{3} have beendeposited onto (100)-oriented LaAlO_{3} (0.1<x<0.5) substrates using the PulsedLaser Deposition technique. While for some compositions the physical properties(transport and magnetization) of the as-grown films are higher than the bulkvalues, for other calcium contents the optimized properties are obtained onlyafter annealing under oxygen. These data can be partly explained by changes inoxygen content, resulting in cationic vacancies and thus self-doping effects -accompanying structural changes, may be the cause of properties beyond thephase diagram. We propose a new phase diagram for(La_{1-x}Ca_{x})_{1-y}\square_{y}MnO_{3} (0.1<x<0.5) thin films.Comment: 8 pages, 5 figures submitted to Applied Physics Letter
