Abstract
We prepared thin films of La0.67Ca0.33MnO3 on different substrates with DC sputtering. The measured transport and magnetic properties could be explain ed 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 c harge carriers in magnetic field. (C) 1999 Elsevier Science B.V. All rights reserved.
