Abstract We prepared thin films of La 0.67 Ca 0.33 MnO 3 on different substrates with DC sputtering. The measured transport and magnetic properties could be explained by a lattice mismatch induced by the substrate. Hall effect measurements showed a holelike charge carrier density n * h = 1.3 per unit cell below T C . The magnetoresistance results from an increase of the mobility of the charge carriers in magnetic field.
